Cellular respiration

Question 1

ATP

Answer 1

Able to store energy due to negative charge

Question 2

PHOSPHORYLATION

Answer 2

• Breaking the terminal group of an ATP/ADP molecule and transferring it to another molecule.
• Molecule becomes temporarily energetic and able to perform cellular work

Question 3

METABOLISM

Answer 3

The sum of all BIOCHEMICAL REACTIONS in the BODY

Question 4

CATABOLIC

Answer 4

Break down

Question 5

ANABOLIC

Answer 5

Build up

Question 6

ACR equation

Answer 6

glucose + 6 oxygen —> 6 water + 6 carbon dioxide (+36atp)

Question 7

Where does glycolysis occur?

Answer 7

cytosol

Question 8

Where does the Krebs cycle occur?

Answer 8

in the matrix of the mitochondria

Question 9

Where does the Electron Transport Chain occur?

Answer 9

in the cristae of the mitochondria

Question 10

Name the products of glycolysis in aerobic respiration

Answer 10

2 pyruvate, 2ATP and 2 NADH

Question 11

Name the products of the Krebs cycle

Answer 11

Carbon dioxide and 8NADH, 2 FADH2 and 2 ATP.

Question 12

Name the products of the Electron Transport Chain

Answer 12

26-28 ATP. Water, 10 NAD+ 2 FAD+

Question 13

How many ATP are made in aerobic respiration?

Answer 13

30-32 ATP

Question 14

How many ATP are made in anaerobic respiration?

Answer 14

2 ATP

Question 15

How many net ATP are made in glycolysis?

Answer 15

2 ATP

Question 16

How many net ATP are made in the Krebs cycle?

Answer 16

2 ATP

Question 17

How many net ATP are made in the Electron Transport Chain?

Answer 17

26-28ATP

Question 18

Describe the process of glycolysis

Answer 18

6-C glucose is broken into 2 pyruvic acids (3-C) creating 2ATP and 2NADH

Question 19

Describe the process of the Krebs cycle

Answer 19

Removal of H+ions from pyruvate creating loaded coenzymes and CO2 as a waste product

Question 20

Describe the process of the Electron Transport Chain

Answer 20

H+ ions are pumped across the membrane creating a concentration gradient that drives the synthesis of ATP. Hydrogen rushes back across the mebrane (ATP synthase). Oxygen is the final acceptor of the H+ ions and electrons forming water.

Question 21

Which part of aerobic respiration doesn’t actually require oxygen?

Answer 21

Glycolysis (this would therefore occur in both anaerobic and aerobic)

Question 22

List 4 metabolic processes that require ATP

Answer 22

muscle contraction
Active transport
Cell division
thermogenesis

Question 23

what is the purpose of NADH and FADH2 molecules produced during glycolysis and the krebs cycles?

Answer 23

serves as a carrier of high-energy electrons and protons to the ETC to facilitate the generation of ATP
