Q: Which equation correctly represents cellular respiration?

$$C_6H_{12}O_6$ + 6O_2 \rightarrow 6CO_2 + 6H_2O + \text{energy}$$

Question 1

Which of the following correctly represents the overall chemical equation for photosynthesis?

Accepted Answer

$$6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6$ + 6O_2$$

Question 2

Which organelle is primarily responsible for cellular respiration in eukaryotic cells?

Accepted Answer

Mitochondrion

Question 3

During photosynthesis, which molecule acts as the main energy source driving the reaction?

Accepted Answer

Sunlight

Question 4

Which of the following is a product of cellular respiration?

Accepted Answer

Carbon dioxide

Question 5

If a plant is kept in the dark for several days, which process will be most directly affected?

Accepted Answer

Photosynthesis

Question 6

Which of the following best describes the relationship between photosynthesis and cellular respiration?

Accepted Answer

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy.

Question 7

What would most likely happen to animals if the oxygen produced by plants during photosynthesis was suddenly removed from the atmosphere?

Accepted Answer

Animals would be unable to perform cellular respiration and would eventually die.

Question 8

Which of the following substances is recycled between photosynthesis and cellular respiration?

Accepted Answer

Carbon dioxide and oxygen

Question 9

A meteor impact blocks sunlight from reaching Earth for several months. Based on the model, what is the most immediate effect on the biosphere?

Accepted Answer

Photosynthesis in plants decreases, leading to less oxygen and food production.

Question 10

Which equation correctly represents cellular respiration?

Accepted Answer

$$C_6H_{12}O_6$ + 6O_2 ightarrow 6CO_2 + 6H_2O + 	ext{energy}$$

Question 11

Which of the following is NOT required for photosynthesis to occur?

Accepted Answer

Oxygen

Question 12

If you forget to water your plants, which reactant of photosynthesis is most directly limited?

Accepted Answer

Water

Question 13

Which organelle is found in plant cells but not in animal cells and is essential for photosynthesis?

Accepted Answer

Chloroplast

Question 14

During cellular respiration, what is the primary purpose of glucose?

Accepted Answer

To provide energy for the cell

Question 15

Which of the following best explains why plants are essential for animal survival?

Accepted Answer

Plants produce glucose and oxygen through photosynthesis, which animals need for cellular respiration.

Question 16

A student claims that cellular respiration only occurs in animals. Which evidence from the model disproves this claim?

Accepted Answer

Cellular respiration occurs in mitochondria, which are found in both plant and animal cells.

Question 17

Which process directly converts solar energy into chemical energy stored in glucose?

Accepted Answer

Photosynthesis

Question 18

If a plant cell's mitochondria are damaged, which process will be most affected?

Accepted Answer

Cellular respiration

Question 19

Which of the following is a reactant in cellular respiration?

Accepted Answer

Oxygen

Question 20

Which of the following statements best explains how energy flows from the sun to animals?

Accepted Answer

Sunlight is absorbed by plants during photosynthesis, producing glucose, which is then consumed by animals and used in cellular respiration to release energy.
