• Fungi

• Unicellular aquatic eukaryotes

In a plant, which of the following reactions produce molecular oxygen (O2)?

• The Calvin cycle alone

• The light reactions and the Calvin cycle

• The light reactions alone

• Neither the light reactions nor the Calvin cycle

Which of the following occurs during the Calvin cycle?

• Carbon Fixation

• Release of oxygen

• Generation of CO2

• Reduction of NADP+

What are the products of linear electron flow in the light reactions of photosynthesis?

• heat and fluorescence

• ATP and P700

• ADP and NADP+

• ATP and NADPH

Which letter to the right shows the enzyme's activation energy?

• a

• b

• e

• d

A greenhouse becomes excessively hot from too much sunlight. One solution is to shade the plants with colored translucent plastic sheets, the color of which allows passage of only that wavelength of light. Which of the following colors would reduce the overall light without reducing plant growth?

• Orange

• Blue

• Yellow

• Green

Which of the following statements about the process of glycolysis is correct?

• Glycolysis requires oxygen to produce ATP.

• Glycolysis occurs in the mitochondria of the cell.

• Glycolysis results in a net production of 2 ATP molecules.

• Glycolysis produces 36 ATP molecules for each molecule of glucose.

Which of the following best describes the role of NAD+ in cellular respiration?

• It is the final electron acceptor in the electron transport chain.

• It helps in the synthesis of ATP during glycolysis.

• It acts as an electron carrier, transporting electrons to the electron transport chain.

• It directly produces ATP by substrate-level phosphorylation.

What is the primary purpose of the electron transport chain in cellular respiration?

• To generate carbon dioxide and water.

• To create a protein gradient across the inner mitochondrial membrane.

• To produce ATP directly through substrate-level phosphorylation.

• To reduce oxygen in water.

Which of the following molecules is produced during both the light reactions of photosynthesis and glycolysis?

• NADH

• NADPH

• ATP

• O2
