Helps to produce H2O

Question 10

Where in a plant or animal cells do aerobic (A) and anaerobic (B) respiration occur?

Answer 10

A: Mitochondria B: Cytoplasm

Question 11

How does cellular respiration maintain homeostasis at a cellular level?

Answer 11

Maintaining oxygen and CO2 by eating food

Question 12

What happens to carbon dioxide produced by cellular respiration?

Answer 12

It is recycled back into the system by plants by the process of photosynthesis

Question 13

How is the chemical energy in glucose similar to money in a saving account?

Answer 13

We save up ATPs that we can use later like saving money to use later.

Question 14

Answer 14

36 ATPs

Question 15

What does it mean if a process is anaerobic? Anaerobic does not need oxygen. Which part of cellular respiration is anaerobic?

Answer 15

Glycolysis is the part of cellular respiration that is anaerobic also goes in fermentation.

Question 16

Name 2 types of fermentation

Answer 16

Lactic-acid Fermentation(follows glycolysis)

1. Turns pyruvate into lactic acid
2. Occurs in skeletal muscle during anaerobic exercise
3. Used to make cheese,yogurt, sour cream

Alcoholic Fermentation

1. Yeast and bacteria use this process
2. Use pyruvate to make ethyl alcohol and carbon dioxide
3. Use to make breads, beers, and wines

Question 17

How do organisms generate energy when oxygen is not available?

Answer 17

Anaerobic respiration (glycolysis and fermentation)

Question 18

Why do muscles of runners sometimes produce lactic acid

Answer 18

Go into Anaerobic respiration bc not enough oxygen

Question 19

Why do runners breathe heavily after a sprint race?

Answer 19

Could not take in enough oxygen while running

Question 20

Bread rises as a result of yeast fermentation. How might fermentation causes bread to rise?

Answer 20

fermentation gives off Carbon Dioxide and alcohol. Alcohol evaporates
