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