Remediation - Photosynthesis and Cell Respiration

Which statement best describes photosynthesis and respiration?

• Autotrophs carry out photosynthesis, while autotrophs and heterotrophs carry out respiration.

• Autotrophs and heterotrophs both carry out photosynthesis and then respiration.

• In autotrophs, photosynthesis requires oxygen, and respiration requires carbon dioxide.

• Only autotrophs carry out photosynthesis, while only heterotrophs carry out respiration.

Where is ATP produced?

• only in autotrophs

• only in heterotrophs

• in plant and animal cells only

• in all cells

Some parasites live in the intestines of the host where there is no oxygen. Which process is the best mode for these parasites to get the energy needed to stay alive?

• aerobic respiration

• anaerobic respiration

• chemosynthesis

• photosynthesis

When athletes run long distances, their muscles become fatigued due to a lack of oxygen. Which process helps athletes generate more energy to continue running?

• aerobic respiration

• anaerobic respiration

• chemosynthesis

• photosynthesis

How are the reactions of photosynthesis and cellular respiration interconnected?

• The reactions are opposites of one another, each using the products of the other as reactants.

• Both reactions require ATP as the energy source, but photosynthesis only happens in plants.

• Every organism carries out both processes at the same time but in different parts of the organism.

• Animals rely on photosynthesis in plants, and plants rely on respiration as the source for their ATP.

What are the products of photosynthesis?

• O₂, C₆H₁₂O₆

• CO₂, H₂O

• CO₂, C₆H₁₂O₆

• O₂, H₂O

How is respiration different from photosynthesis?

• Respiration involves the transformation of energy.

• Respiration involves the exchange of gases.

• Respiration is a process that occurs in cells.

• Respiration takes place in all living things.

Photosynthesis is an energy conversion process. Which pathway shows the energy transformations that occur from the beginning to the end of the process?

• solar --> glucose --> ATP

• glucose --> ATP --> solar

• solar --> ATP --> glucose

• glucose --> solar --> ATP

What can be concluded from the diagram?

• Photosynthesis provides oxygen for cellular respiration.

• Cellular respiration provides light energy for photosynthesis.

• Photosynthesis releases water that is used for cellular respiration.

• Cellular respiration produces glucose that is used in photosynthesis.

How does aerobic respiration differ from anaerobic respiration?

• Aerobic respiration uses cellulose as a substrate to yield roughly 2 ATPs, while anaerobic respiration uses cellulose as a substrate to yield 38 ATPs.

• Aerobic respiration uses cellulose as a substrate to yield roughly 2 ATPs, while anaerobic respiration uses glucose as a substrate to yield 38 ATPs.

• Aerobic respiration uses glucose as a substrate to yield roughly 38 ATPs, while anaerobic respiration uses cellulose as a substrate to yield 2 ATPs.

• Aerobic respiration uses glucose as a substrate to yield roughly 38 ATPs, while anaerobic respiration uses glucose as a substrate to yield 2 ATPs.
