Cell Respiration, Biogeochemical Cycles, and Photosynthesis Test

Photosynthesis means "light" "breaking". Use the model to determine which molecule the light is breaking.

• The electron transport chain

• water

• carbon dioxide

• oxygen

Refer to the model to determine where the oxygen we breathe came from.

• water

• carbon dioxide

• glucose

• atp

Use the model to determine where hydrogen in glucose originates.

• water

• carbon dioxide

• nadph

• atp

If the process illustrated in the diagram is interrupted by a chemical that disrupts the ETC, there would be an immediate effect on the release of which byproduct?

• glucose

• carbon dioxide

• chlorophyll

• oxygen

Where do the light reactions of photosynthesis occur?

• In the stroma

• In the thylakoids

• In the mitochondria

• In the cristae

How many glucose molecules are produced from 6 carbon dioxide molecules and 12 water molecules during photosynthesis?

• 1

• 4

• 6

• 38

What is the chemical equation for photosynthesis?

What is the role of chlorophyll in energy conversion?

• Chlorophyll converts chemical energy into radiant energy

• Chlorophyll excites photons of light energy and stores them

• Chlorophyll converts oxygen and nutrients in order to drive metabolic activities

• Chlorophyll absorbs light and converts it to chemical energy

Where does glycolcysis occur?

• Mitochondria

• chloroplasts

• cytoplasm

• thylakoids

Where does aerobic respiration (the krebs cycle and ETC) occur?

• mitochondria

• cytoplasm

• chloroplasts

• endoplasmic reticulum
