1A cell requires energy to... (choose the CORRECT statements.)
- Amake new materials.
- Bgrow.
- Cmove.
- Dpump ions across membranes.
2Which statement about compartmentalised energy production is INCORRECT?
- AGlycolysis occurs in the sER.
- BThe citric acid cycle occurs in the mitochondria.
- COxidative phosphorylation occurs in the mitochondrial membrane.
3Cellular respiration releases chemical energy from food using mechanical energy.
- AVerdadeiro
- BFalso
4Which statement about the mitochondria is NOT correct?
- AMitochondria contain ribosomes and mitochondrial DNA in their matrix.
- BThe mitochondria has two phospholipid bilayers, with specific proteins integrated into these.
- CThe mitochondria's inner membrane has cristae to increase surface area and efficiency of organelle function.
- DThe mitochondria can change shape, fuse and divide, and form branched networks.
- EMitochondria are capable of producing all their own necessary proteins.
5Choose the CORRECT statements about glycolysis.
- AGlycolysis occurs in the cytosol.
- BGlycolysis breaks down glucose into pyruvate, smaller more manageable units.
- CGlycolysis occurs after the Krebs Cycle.
- DGlycolysis releases energy and electrons.
6Choose the INCORRECT statement about the Krebs cycle.
- AIt is also known as the Citric Acid Cycle.
- BIt uses energy(ATP).
- CIt produces electrons for the carried NAD and FAD.
- DIt processes pyruvate from glycolysis.
7Choose the statement about oxidative phosphorylation which is INCORRECT.
- AOxidative phosphorylation is the final step of energy generation in a cell, and release the largest amount of energy(ATP).
- BOxidative phosphorylation is made up of two steps: firstly, chemiosmosis, followed by an electron transport chain.
- COxidative phosphorylation moves H+ up its concentration gradient, where it is used to make ATP in the protein ATP synthase.
- DOxidative phosphorylation occurs in the intermembrane space within the mitochondria.
- EOxidative phosphorylation uses electrons from NADH and FADH.
8The concentration gradient over the mitochondria's membrane is used to generate ATP.
- AVerdadeiro
- BFalso
