Cellular Respiration Study Guide



Cellular Metabolism Overview

Essential Questions:

1) What is cellular respiration (what’s the purpose)?

2) Explain the relationship that occurs between photosynthesis and cellular respiration. Can you make connections within an organism AND connections between organisms globally?

3) Give the equation for photosynthesis and cellular respiration. What are the reactants and what are the products in each equation? (fill in the chart at the end of this study guide)

4) What types of organisms undergo photosynthesis? What types of organisms undergo cellular respiration? (you have to know which organelles are present in cells within types of organisms)

5) Label each of the following as an autotroph or heterotroph place a “p” for undergoes photosynthesis and a “C” if it undergoes cellular respiration next to it. Some might have both.

Animals:

Plants:

Fungus:

Cyanobacteria:

Lactobacillus bacteria:

6) Identify the organelle on the next page.___________________________

8) In what organelle does photosynthesis occur?

9) List several similarities found between a chloroplast and a mitochondria?

10) What types of molecules are broken down through cellular respiration?

11) What are the products of glycolysis?

12) What are the products of Krebs cycle?

13) What’s another name for the Krebs Cycle?

14) What are the products of ETC?

15) What are the products of fermentation?

16) What are some food products that are associated with lactic acid fermentation and alcoholic fermentation?

17) What is the main purpose of fermentation?

18) Explain why a runner may experience a burning sensation while running for a long distance.

19) How much ATP is produced in the various steps of cellular respiration?

20) What determines what happens to the products of glycolysis?

21) Explain the difference between aerobic and anaerobic respiration. What does this mean in terms of efficiency?

22) Fill in the table below comparing and contrasting photosynthesis with cellular respiration.
