Question 10

Catabolic reactions

Answer 10

Breaking down complex substrates to simple, releases energy

Question 11

Anabolic reactions

Answer 11

Simple substrates synthesized into complex ones, requires energy

Question 12

Glycolysis

Answer 12

Breakdown of glucose

Question 13

Aerobic respiration

Answer 13

Uses oxygen, yields 36 ATP per glucose

Question 14

Glycogenolysis

Answer 14

Breakdown of glycogen, to provide glucose to cells

Question 15

Glycogenesis

Answer 15

Production of glycogen, to store for later

Question 16

Gluconeogenesis

Answer 16

Production of new glucose, from fat or protein

Question 17

Lipolysis

Answer 17

Breakdown of fat

Question 18

Fatty acid synthesis

Answer 18

Production of fat

Question 19

Two types of anabolic reactions with carbohydrates

Answer 19

Glycogenesis and gluconeogenesis

Question 20

Anabolic reaction with fat

Answer 20

Fatty acid synthesis

Question 21

Anabolic reaction with protein

Answer 21

Synthesis of non essential amino acids

Question 22

Anabolic vs catabolic

Answer 22

Building up vs breaking down

Question 23

3 catabolic reaction with carbs

Answer 23

Glycolysis, aerobic respiration and glyogenolysis

Question 24

Catabolic reaction with fat

Answer 24

Beta oxidation aka lipolysis

Question 25

Catabolic reaction with protein

Answer 25

Deamination (amino acid degradation)

Question 26

Postabsorptive

Answer 26

Aka fast, more than 6hrs after feeding

Body starts to go into catabolic state and break down stored energy sources from macronutrients

Question 27

Absorptive

Answer 27

Less than 6 hrs after eating

Anabolic or building state, will store and synthesis fat, protein and carbs

Question 28

Basal metabolic rate

Answer 28

Maintain body’s function at rest

Question 29

What factors influence BMR

Answer 29

Muscle mass, Age, body temp, body surface area

Question 30

Metabolic rate

Answer 30

Energy expended added to be BMR (amount of calories needed to maintain current weight)
