Photosynthsis and Cellular Respiration

A student is observing a single-celled alga and knows that it undergoes photosynthesis and respiration. Which question could the student ask to find out how it can do both processes?

• Are the inputs of photosynthesis the same as the outputs of respiration?

• Are the inputs of photosynthesis the same as the inputs of respiration?

• Is water needed for the processes of respiration and photosynthesis?

• Is carbon dioxide needed for the process of photosynthesis?

Why is anaerobic respiration considered less efficient than aerobic respiration?

• Why is anaerobic respiration considered less efficient than aerobic respiration?

• More oxygen is required for anaerobic respiration than for aerobic respiration.

• More ATP molecules are gained in aerobic respiration than in anaerobic respiration.

• Less lactic acid is formed during anaerobic respiration than during aerobic respiration.

When an individual exercises vigorously for more than 15 minutes, the muscle cells are unable to obtain oxygen from the blood quickly enough. As a result, the muscle cells

• stop functioning properly, resulting in cramps

• pull oxygen through the skin in order to continue working

• send signals to the brain telling it to shut the muscles down.

• start anaerobic respiration, producing lactic acid buildup

During the light reaction of photosynthesis, energy becomes stored in the compounds ATP and NADPH. A second set of reactions uses this stored energy to produce vital compounds such as glucose. The second set of reaction involves a biochemical pathway known as

• The Calvin Cycle

• Carbon Fixation

• Photorespiration

• Photo system I

Energy and Oxygen are created from visible sunlight during the

• Light independent reaction

• Calvin Cycle

• Light dependent reaction

• Krebs Cycle

What is the correct sequence of events

• Glycolysis->Krebs Cycle->ETC

• ETC->Glycolysis->Krebs

• Krebs->ETC->Glycolysis
