Cellular Metabolism Part 2

Question 1

the process by which cells take glucose and turn it into usable energy

Answer 1

cellular respiration

Question 2

the chemical energy all cells need to thrive

Answer 2

ATP

Question 3

what is produced in the mitochondria

Answer 3

ATP, carbon dioxide, and water which are made from oxygen, lipids, and carbohydrates

Question 4

Why is ATP an unstable molecule?

Answer 4

it breaks apart easily turning into ADP and phosphate group and releases energy

Question 5

What are the two forms of cellular respirations

Answer 5

1. aerobic

2. anaerobic

Question 6

when cells use glucose and oxygen to produce energy

Answer 6

aerobic respiration

Question 7

aerobic respiration step 1

Answer 7

glycolysis

occurs in the cytoplasm of the cell

Question 8

what does glycolysis not require?

Answer 8

oxygen

Question 9

Aerobic respiration step 2

Answer 9

pyruvate oxidation

occurs in the mitochondrial matrix

Question 10

Aerobic respiration step 3

Answer 10

Krebs cycle or citric acid cycle

Question 11

process of Krebs cycle

Answer 11

during step one Acetyl CoA, 2-carbon combines with a six-carbon molecule

Question 12

What does the Krebs cycle result in?

Answer 12

a. 3 NADH
b. 1 FADH2
c. 1 ATP
d. 2 carbon dioxide
e. another 4-carbon molecule

Question 13

Aerobic respiration step 4

Answer 13

Oxidative Phosphorylation
the electron transport train
occurs in the inner membrane of the mitochondria

Question 14

producing energy without oxygen

Answer 14

Anaerobic cellular respiration

Question 15

what happens in cellular respiration if there is no oxygen after glycolysis

Answer 15

Fermentation until oxygen is available

Question 16

1. occurs in animals, humans, and some bacteria

2. pyruvate from glycolysis bonds to hydrogen creating lactic acid

Answer 16

lactic acid fermentation

Question 17

1. occurs in plants and fungi

2. pyruvate from glycolysis goes through a chemical process that produces alcohol and carbon dioxide

Answer 17

alcoholic fermentation
