Which statement about the mitochondria is NOT correct?

Selecciona una de las siguientes respuestas posibles:

  • 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.

1

Choose the INCORRECT statement about the Krebs cycle.

Selecciona una de las siguientes respuestas posibles:

  • It is also known as the Citric Acid Cycle.

  • It uses energy(ATP).

1

Choose the statement about oxidative phosphorylation which is INCORRECT.

Selecciona una de las siguientes respuestas posibles:

  • 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.

Explicación
