Question

Why is anaerobic respiration energetically less efficient than aerobic respiration?

A: The aerobic respiration process uses a respiratory electron transport chain, while anaerobic respiration uses a molecular electron transport chain.

B: Anaerobes use less oxidizing substances like sulfate or nitrate during the electron transport chain so less energy is released per oxidized molecule.

C: Anaerobes use only oxygen during the electron transport chain, while aerobes use both oxygen and carbon dioxide which results in a more efficient process.

Answer 1

D: Anaerobes' terminal electron receptors have larger reduction potentials than O2 meaning that more energy is released per oxidized molecule.

Answer 14

When an organic compost pile is built correctly (sufficiently large, slightly moist, and containing a variety of organic material), it tends to get hot. Which of the following best explains why a compost pile gets hot?

Answer 15

A: Solar energy hitting the pile causes photosynthetic microorganisms in the pile to begin working and releasing the stored energy as heat.

B: Water molecules within the compost pile spontaneously break down and release their energy as heat.

C: The decomposers are breaking down energy-containing organic molecules for their own use and some of the energy escapes as heat.

D: The decomposers are constantly moving around within the compost pile and the friction of their motion heats up the pile.
