Photosynthesis & Cellular Respiration

The products of this process are glucose and oxygen

• Photosynthesis

• Cellular Respiration

Answer explanation

The process that produces glucose and oxygen is photosynthesis, where plants convert sunlight, carbon dioxide, and water into these products. Cellular respiration, on the other hand, uses glucose and oxygen to produce energy.

This process occurs only in plants

• Photosynthesis

• Cellular Respiration

Answer explanation

Photosynthesis is the process that occurs only in plants, where they convert sunlight into energy. Cellular respiration occurs in both plants and animals, making photosynthesis the correct choice.

The products of this process are carbon dioxide, water, and ATP

• Photosynthesis

• Cellular Respiration

Answer explanation

Cellular respiration is the process that produces carbon dioxide, water, and ATP as byproducts. In contrast, photosynthesis uses carbon dioxide and water to produce glucose and oxygen.

This process occurs in both plants and animals

• Photosynthesis

• Cellular Respiration

Answer explanation

Cellular respiration occurs in both plants and animals as a process to convert glucose into energy. In contrast, photosynthesis only occurs in plants, making cellular respiration the correct choice.

This process has water, carbon dioxide, and sunlight as the reactants

• Photosynthesis

• Cellular Respiration

Answer explanation

Photosynthesis is the process that uses water, carbon dioxide, and sunlight to produce glucose and oxygen. Cellular respiration, on the other hand, uses glucose and oxygen to produce energy, carbon dioxide, and water.

In photosynthesis, water, carbon dioxide, and light energy react to produce glucose and oxygen. Based on the law of conservation of energy, what happened to the light energy in the reaction?

• It was converted into chemical energy stored in the sugar.

• It was neither created nor destroyed.

• It was destroyed.

• It was converted into carbonic acid.

• It was changed into carbon dioxide gas.

Answer explanation

In photosynthesis, light energy is converted into chemical energy stored in glucose. This aligns with the law of conservation of energy, which states energy cannot be created or destroyed, only transformed.

Why are photosynthesis and Cellular respiration considered opposites?

• the reactants of photosynthesis are the same as the reactants of cellular respiration

• the reactants of cellular respiration are the products of photosynthesis

• the products of photosynthesis are the same as the products of cellular respiration

Answer explanation

Photosynthesis produces glucose and oxygen, which are the reactants for cellular respiration. Thus, the reactants of cellular respiration are the products of photosynthesis, making them opposites in their processes.

What is missing in the equation?

C6H12O6 + 6O2 --> 6CO2 + 6 _____ + 36 ATP

Answer explanation

In the equation for cellular respiration, glucose (C6H12O6) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). Therefore, the missing component is H2O, making the correct answer H2O.

If oxygen is not present, then only ____ ATP molecules are made. (the answer is a number)

Answer explanation

In the absence of oxygen, cellular respiration cannot proceed through aerobic pathways, resulting in the production of 0 ATP molecules. Therefore, the correct answer is 0.
