Antworten
-
Glycolysis occurs in the sER.
-
The citric acid cycle occurs in the mitochondria.

Oxidative phosphorylation occurs in the mitochondrial membrane.
Frage 3
Frage
Cellular respiration releases chemical energy from food using mechanical energy.
Frage 4
Frage
Which statement about the mitochondria is NOT correct?
Antworten
-
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.
Frage 5
Frage
Choose the CORRECT statements about glycolysis.
Antworten
-
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.
Frage 6
Frage
Choose the INCORRECT statement about the Krebs cycle.
Antworten
-
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.
Frage 7
Frage
Choose the statement about oxidative phosphorylation which is INCORRECT.
Antworten
-
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.
Frage 8
Frage
The concentration gradient over the mitochondria's membrane is used to generate ATP.
