L9 Energy in the Cell

Question 1 of 8

1

A cell requires energy to... (choose the CORRECT statements.)

Select one or more of the following:

  • make new materials.

  • grow.

  • move.

  • pump ions across membranes.

Explanation

Question 2 of 8

1

Which statement about compartmentalised energy production is INCORRECT?

Select one of the following:

  • Glycolysis occurs in the sER.

  • The citric acid cycle occurs in the mitochondria.

  • Oxidative phosphorylation occurs in the mitochondrial membrane.

Explanation

Question 3 of 8

1

Cellular respiration releases chemical energy from food using mechanical energy.

Select one of the following:

  • True
  • False

Explanation

Question 4 of 8

1

Which statement about the mitochondria is NOT correct?

Select one of the following:

  • 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.

Explanation

Question 5 of 8

1

Choose the CORRECT statements about glycolysis.

Select one or more of the following:

  • 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.

Explanation

Question 6 of 8

1

Choose the INCORRECT statement about the Krebs cycle.

Select one of the following:

  • 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.

Explanation

Question 7 of 8

1

Choose the statement about oxidative phosphorylation which is INCORRECT.

Select one of the following:

  • 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.

Explanation

Question 8 of 8

1

The concentration gradient over the mitochondria's membrane is used to generate ATP.

Select one of the following:

  • True
  • False
