Cellular Respiration and Photosynthesis

Which molecules are required to carry out photosynthetic production of organic substances?

• Carbon dioxide

• Oxygen

• NADH

• Water

• ATP

The citric acid cycle occurs:

• In the intermembrane space

• In the thylakoids

• In the stroma

• In the mitochondrial matrix

• In the mitochondrial cristae

Which processes are classified as substrate-level phosphorylation?

• The Calvin cycle

• Chemiosmosis

• Glycolysis

• Citric acid cycle

• Electron transport

The final electron acceptor of the electron transport chain in photosynthesis is:

• Carbon dioxide

• NAD+

• Water

• Oxygen

• NADP+

Photorespiration is commonly found in which type of plant?

• CAM

• C3

• Bundle-sheath

• Mesophyll

• C4

Production of ATP and NADPH is due to necessity of energy to power which process?

• Light reactions

• Electron transport chain

• Calvin cycle

• Citric acid cycle

• Chemiosmosis

How do CAM plants behave under arid conditions?

• Closing stomata during the day and opening them during the night

• Opening stomata during the day and closing them at night

• Using only bundle-sheath cells to fix carbon

• Use bundle-sheath and mesophyll cells to help fix carbon and prevent photorespiration

Cellular respiration is an oxidative reaction, while photosynthesis is:
