semi- Final Exam. in Developmental Genetics/ Cellular Physiology

Which of the following statements is true?

• Plants and animals release oxygen during respiration.

• Plants and animals use oxygen during respiration.

• Plants use oxygen during photosynthesis.

• Plants release only carbon dioxide during photosynthesis.

The energy required to break apart glucose and oxygen during cellular respiration is 2,000 kcal.

The energy released during the formation of carbon dioxide and water during cellular respiration is 3,000 kcal.

Identify whether more energy is required or released during cellular respiration.

• More energy is released during cell respiration

• More energy is required during cell respiration

• The amount of energy required and released is equal

• There is no way to determine the answer

The difference in the energy released versus the energy required to break apart the reactants during cellular respiration is stored in energy carrying molecules (called ATP) and released as:

• Light

• Heat

• Food

• Oxygen
