ANP1105 ORGANELLES EXAM
QUESTIONS WITH 100% CORRECT
ANSWERS | LATEST VERSION 2025/2026.
Plasma membrane structure - ANS Phospholipid bilayer in which proteins and cholesterol are
embedded
Plasma membrane function - ANS External cell barrier: transmembrane proteins acts as
receptors for chemical messengers, as transport proteins, and in cell-to-cell recognition.
Maintains a resting potential for excitable cells.
Cytoplasm - ANS Cellular region between nuclear and plasma membranes. Consists of
cytosol (fluid), organelles (metabolic machinery), and inclusions (stored nutrients, secretory
products, pigment granules).
Mitochondria - structure - ANS Double-membrane; inner membrane folded into cristae
(projections)
Mitochondria - function - ANS Site of ATP synthesis; powerhouse of the cell.
Ribosomes - structure - ANS Composed of two subunits, each composed of ribosomal RNA
and protein. Free or attached to rough ER
Ribosomes - function - ANS Sites of protein synthesis
