Energy & Respiration - exam practice

The following reactions all occur in mitochondria during aerobic respiration:

1 - decarboxylation of pyruvate

2 - reduction of NAD

3 - substrate level phosphorylation of ATP

Which reaction(s) take place outside the mitochondria in yeast cells?

What is the net gain in ATP molecules following the glycolysis of one glucose molecule?

What is the number of molecules of triose phosphate required to produce two molecules of glucose?

Which statement(s) is/are true of anaerobic respiration in both animal and yeast cells?

1 - pyruvate is produced in glycolysis

2 - reduced NAD is oxidised

3 - two molecules of ATP are produced net, per glucose molecule

Cellular respiration occurs in different regions of a cell.

In which region is FADH₂ produced?

The balanced equation for the aerobic respiration of a substrate is given below:

2 C₁₈H₃₄O₂ + 51 O₂ → 36 CO₂ + 34 H₂O

Which statement gives the correct respiratory quotient (RQ) and identity of this substrate?

Which option correctly identifies the products of anaerobic respiration in yeast?

Proton pumps establish electrochemical gradients, which are required for ATP production.

Which regions of a plant cell are protons pumped into?

What is a similarity in the way ATP is made in respiration and photosynthesis?

Which statement describes and explains the relative yield of ATP in anaerobic and aerobic respiration?
