1Which cellular organelle is the primary site of ATP generation by oxidative phosphorylation?

A.Golgi apparatus

B.Peroxisome

C.Rough endoplasmic reticulum

D.Mitochondrion

Explanation: Mitochondria generate most cellular ATP through oxidative phosphorylation along the inner mitochondrial membrane electron transport chain. Rough ER synthesises proteins; Golgi modifies and sorts them; peroxisomes handle peroxide metabolism and very-long-chain fatty acid oxidation.

2Which cytoskeletal filament is composed of actin monomers and drives cell motility and contractile force?

A.Nuclear lamina filaments

B.Intermediate filaments

C.Microtubules

D.Microfilaments

Explanation: Microfilaments are actin polymers that mediate cell shape, motility, and contractile functions with myosin. Intermediate filaments provide tensile strength; microtubules organise intracellular transport and mitosis; nuclear lamina filaments (lamins) support the nuclear envelope.

3Growth factors typically activate receptor tyrosine kinases. What is the immediate intracellular consequence of ligand binding?

A.Irreversible receptor proteolysis in the cytosol

B.Immediate opening of nuclear pores for mRNA export

C.Direct DNA transcription without phosphorylation

D.Receptor dimerisation and autophosphorylation on tyrosine residues

Explanation: Ligand binding induces receptor tyrosine kinase dimerisation and autophosphorylation, creating docking sites for signalling adapters (e.g., Grb2, PLC-γ). This initiates cascades such as RAS–MAPK and PI3K–AKT that regulate growth and survival, rather than immediate DNA binding or nuclear pore opening.

4Which process describes removal of damaged organelles by sequestering them in autophagosomes that fuse with lysosomes?

A.Pyroptosis

B.Entosis

C.Necroptosis

D.Autophagy

Explanation: Autophagy sequesters damaged organelles and proteins in double-membrane autophagosomes that fuse with lysosomes for degradation and recycling. Necroptosis and pyroptosis are forms of regulated necrosis/inflammatory death; entosis is cell-in-cell engulfment, not lysosomal recycling of organelles.

5How is the ATF6 branch of the unfolded protein response activated during endoplasmic reticulum stress?

A.Mitochondrial cytochrome c release activating ATF6

B.IRE1 signalling alone, without any ATF6 pathway

C.PERK directly cleaving ATF6 in the cytosol

D.ATF6 translocation to the Golgi followed by proteolytic activation

Explanation: ATF6 is itself one of the three ER stress sensors. Under ER stress it relocates from the ER to the Golgi, where site-1 and site-2 proteases release an active transcription-factor fragment that upregulates chaperones. IRE1 and PERK are parallel UPR sensors; cytochrome c release is an apoptotic mitochondrial event, not ATF6 activation.

6Which statement best describes the function of gap junctions between adjacent cells?

A.They anchor intermediate filaments to the basement membrane

B.They mediate calcium-independent vesicle fusion at synapses

C.They form impermeable seals that prevent paracellular leakage

D.They allow passage of small ions and metabolites between neighbouring cytoplasms

Explanation: Gap junctions (connexin channels) permit direct cytoplasmic exchange of ions and small molecules, coordinating tissue responses. Tight junctions seal paracellular routes; hemidesmosomes anchor intermediate filaments to basement membrane; synaptic vesicle fusion is a separate specialised process.

7Which histone modification is most strongly associated with transcriptionally active euchromatin?

A.DNA cytosine methylation at CpG islands

B.Histone H3 lysine 9 trimethylation (H3K9me3)

C.Histone H3 lysine 27 trimethylation (H3K27me3)

D.Histone H3 lysine 4 trimethylation (H3K4me3)

Explanation: H3K4me3 near promoters marks active transcription in euchromatin. H3K9me3 and H3K27me3 are repressive marks typical of heterochromatin. DNA methylation at CpG islands usually represses transcription and is not a histone modification.

8Which extracellular matrix component is the principal structural protein providing tensile strength in connective tissue?

A.Elastin

B.Hyaluronic acid

C.Type I collagen

D.Fibronectin

Explanation: Type I collagen is the most abundant fibrillar collagen and supplies tensile strength to bone, dermis, and many connective tissues. Elastin provides recoil; hyaluronic acid is a glycosaminoglycan that retains water; fibronectin mediates cell–matrix adhesion but is not the main tensile scaffold.

9Reversible cell injury is most characteristically associated with which morphologic change?

A.Formation of apoptotic bodies with intact neighbouring membranes

B.Caseous necrosis with granuloma formation

C.Nuclear karyolysis with membrane rupture

D.Cellular swelling and fatty change

Explanation: Early reversible injury shows cellular (hydropic) swelling from failed Na+/K+ ATPase and fatty change from impaired lipid metabolism. Nuclear dissolution with membrane rupture indicates necrosis; apoptotic bodies define apoptosis; caseous necrosis is irreversible tissue death, often with granulomas.

10Which pattern of necrosis is typical of hypoxic death in solid organs such as heart, kidney, and spleen?

A.Fat necrosis

B.Fibrinoid necrosis

C.Liquefactive necrosis

D.Coagulative necrosis

Explanation: Coagulative necrosis preserves tissue architecture temporarily after ischaemic injury in most solid organs because enzymatic digestion is delayed. Liquefactive necrosis dominates in brain infarcts and abscesses; fat necrosis occurs in pancreatitis/trauma; fibrinoid necrosis affects vessel walls in immune injury.

About the RCPA BPS Exam Exam

The RCPA Basic Pathological Sciences (BPS) examination is the College's foundational pathology knowledge assessment. It tests mechanisms of disease across pathology disciplines using Robbins-aligned general pathology, plus research methods and laboratory error-reduction principles. The 2026 paper is a 105-item online invigilated MCQ lasting 2.5 hours.

Assessment

Single online invigilated multiple-choice paper covering the RCPA Basic Pathological Sciences syllabus. Sections 1–11 follow the first eleven chapters of Robbins and Cotran Pathologic Basis of Disease; sections 12–13 cover research concepts and error reduction/prevention. Mandatory for RCPA trainees and available to students and other health professionals.

Time Limit

2.5 hours (150 minutes)

Passing Score

College standard-set each sitting; RCPA does not publish a fixed percentage cut-score for BPS. Confirm current rules with the College.

Exam Fee

Students (medical/science/dental/allied health): AUD $200; other applicants: AUD $800 (as published on the RCPA BPS page — confirm for your sitting). (Royal College of Pathologists of Australasia (RCPA))

RCPA BPS Exam Study Tips from Top Performers

1Work through Robbins and Cotran chapters 1–11 in order — RCPA maps BPS sections 1–11 directly to those chapters — then add dedicated notes for research methods and laboratory error reduction (sections 12–13).

2Drill mechanism-level distinctions that recur in SBA stems: coagulative vs liquefactive necrosis, type II vs III vs IV hypersensitivity, oncogene vs tumour-suppressor hits, and red vs pale infarcts.

3For laboratory/error items, practise the error timeline (pre-pre-analytical test choice → pre-analytical ID/collection → analytical IQC → post-analytical reporting) so you can classify vignettes quickly under time pressure.

Frequently Asked Questions

What is the RCPA Basic Pathological Sciences (BPS) exam?

BPS is the Royal College of Pathologists of Australasia's foundational multiple-choice examination on mechanisms of disease. It is mandatory for RCPA pathology trainees and is also open to medical, science, dental and allied health students and other applicants. Content follows a 13-section syllabus based largely on Robbins and Cotran general pathology, plus research concepts and error reduction.

How many questions and how much time does the official BPS paper allow?

For 2026, RCPA states the BPS paper has 105 multiple-choice questions (50 with four options and 55 with five options) over 2.5 hours, delivered online with invigilation. This free practice set uses 100 four-option items mapped to the same syllabus sections.

How much does the RCPA BPS exam cost?

RCPA has published fee bands of AUD $200 for current medical, science, dental or allied health students and AUD $800 for other applicants. Always confirm the fee for your category and sitting on the official RCPA BPS registration information, because fees can change.

What score do I need to pass BPS?

RCPA does not publish a single fixed percentage pass mark for BPS. The College uses standard-setting for each examination sitting. Unofficial third-party reports have described cohort pass rates around 80–85% in some recent years, but you should rely on College communications for your attempt.
