9. B

10. A

11. C

Explanation:

9.

All cells require energy to power their life processes. Therefore all cells must carry some form of cellular respiration that is designed to provide energy for these processes. Usually, some form of nutrient for the cell, like glucose, is broken down, and the energy in the binds used to power the cell’s activities.

10.

ATPs are the energy currency of cells. Energy is stored in its phosphate bonds. When a cell requires energy, ATPs molecules are broken down to ADP + Pi and the energy in the broken bond is used to power the activity.  The more energy is required the more ATPs are broken down. Some of this energy, however, is lost as heat energy since the process of transformation of energy is inherently inefficient.

11.

When the plant is exposed to sunlight, the light stage of photosynthesis is very active. This phase involves the use of sunlight energy to split water molecules so as to harness the high energy electrons that emanate from this process called photolysis. The energy of the electrons is harnessed to make ATPs by photophosphorylation. Oxygen is usually evolved as a byproduct. Therefore the high activity of the light stage means more oxygen is evolved.

Cellular respiration simply means how cells break up sugars in order to get energy which is used by the body. It should be noted that all living organisms carry out some form of cellular respiration.

In cells, energy is released in small, controlled amounts. ATP is the primary form of energy for the cell. When ATP is converted to ADP, energy is released.

In conclusion, the correct options are B, A, and C.
