Question 1

What function does ATP carry out in living things?

Answer 1

Used to capture and transfer energy

Question 2

The diagram below shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur.

Answer 2

Carbon dioxide and water released by cellular respiration are used in photosynthesis

Question 3

Which of the following are some of the reactants of photosynthesis?

Answer 3

Carbon dioxide and water

Question 4

Based on your knowledge and the diagram below, what gas is produced in the red area labeled as D?

Answer 4

oxygen

Question 5

Based on your knowledge and the diagram below, what molecule enters the chloroplast in the blue area labeled as B?

Answer 5

water

Question 6

The conversion of different molecules is common in all forms of cellular energy. One of these processes in photosynthesis that involves taking in carbon dioxide gas and making sugar is called

Answer 6

Light independent reactions/calvin cycle

Question 7

The stage of photosynthesis that involves breaking apart water and creating oxygen gas is called

Answer 7

Light dependent reaction/ photosynthesis

Question 8

If a plant’s chloroplast is damaged and the stroma is not able to carry out its function, what molecule would not be made / produced?

Answer 8

sugar

Question 9

Which gas is removed from the atmosphere of the plant and used during the process of the Light independent reactions/Calvin cycle of photosynthesis?

Answer 9

carbon dioxide

Question 10

Glycolysis is important because it is responsible for creating a small amount of energy before which of the following processes?

Answer 10

Alcohol fermentation, aerobic cell respiration, lactic acid fermentation

Question 11

How are cellular respiration and photosynthesis related, in terms of energy?

Answer 11

The energy captured in photosynthesis is used to power cellular respiration

Question 12

In which way are photosynthesis and cellular respiration different?

Answer 12

Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide

Question 13

Which statement describes how photosynthesis and cellular respiration are interrelated?

Answer 13

Carbon dioxide and water released by cellular respiration are used in photosynthesis

Question 14

A potted plant is placed inside a clear, sealed vacuum container with no gas inside the container at all. It also has water pumped into it on a regular basis. The container is placed in the sun and the plant’s growth is monitored. Which statement best describes what will most likely happen to the plant over time?

Answer 14

The plant will die because it does not have carbon dioxide for photosynthesis

Question 15

Michelle has four aquatic plants of the same size and the same species. She submerges the plants in a separate beaker filled with 200 ml of water. She then sets each beaker under a different intensity of light. Michelle observes that, of the four plants, the plant in the beaker under the most intense light gives off the most gas bubbles in a 20 minute period. Which of the following statements best explains Michelle’s observations?

Answer 15

Photosynthesis occurs at the highest rate under the most intense light

Question 16

Which process takes place in the presence of oxygen and produces nearly 20 times as much as ATP as glycolysis alone?

Answer 16

Aerobic respiration

Question 17

Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which conclusion can be made from these observations?

Answer 17

Only species y is anaerobic

Question 18

A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?

Answer 18

As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amount of atp in the absence of oxygen

Question 19

Which process do the animals in a food web or food chain use to convert energy from “food” into ATP?

Answer 19

Cellular respiration

Question 20

Human brain cells are some of the few cells in a human that do not undergo any form of fermentation. Which of the following might explain why even a short period of time without oxygen might result in the death of brain cells?

Answer 20

Because the cells would not be able to produce atp in order to function

Question 21

How do photosynthesis and cellular respiration form a cycle of energy storage and use?

Answer 21

Photosynthesis stores energy in sugar; cell respiration releases energy from those sugars

Question 22

Which of the following diagrams accurately represents the use of gases in both cellular respiration and photosynthesis?

Answer 22

a

Question 23

. A diagram representing the relationship between photosynthesis and cellular respiration is shown below. The numbered boxes in the diagram represent which of the following?

Answer 23

a. 1-oxygen; 2- carbon dioxide

Question 24

24. The diagram below shows a cross section of a plant leaf. How does the structure marked as the stoma contribute to the survival of the plant?

Answer 24

It allows the intake of gasses necessary for photosynthesis

Question 25

25. Transpiration is a process in plants that allows them to release gases or intake gases for metabolic processes. Which of the following structures are likely involved in this gas exchange process? In other words, what parts of a plants leaf allows for gasses like oxygen, carbon dioxide, and water to move in/out of the plant?

Answer 25

stoma, guard cells
