Metabolism

Question 1

metabolism

Answer 1

process which allows us to release energy from carbs, fat, protein, and alcohol and synthesize new substances/excrete waste

Question 2

anabolic reactions

Answer 2

using small compounds to build larger ones (building of compounds)
–>use of energy to build

Question 3

catabolic reactions

Answer 3

breaking down compounds
–>production of energy by breaking down

Question 4

ATP (what is it and how is it used)

Answer 4

source of energy at the cellular level; it is used to synthesize new compounds, contract muscles, conduct nerve impulses, pump ions across membranes

Question 5

oxidation

Answer 5

substance is oxidized when it loses 1 or more electrons or hydrogen and gains oxygen

Question 6

reduction

Answer 6

substance is reduced when it gains 1 or more electron and loses oxygen

Question 7

aerobic

Answer 7

when oxygen is readily available

Question 8

anerobic

Answer 8

when adequate oxygen is not present

Question 9

glycolysis

Answer 9

process in which glucose is oxidized to form 2 molecules of pyruvate, NADH +H+, and 2 net molecules of ATP (generates energy; does not require oxygen)

Question 10

citric acid cycle (krebs cycle)

Answer 10

acetyl-coA produces NADH+H+ and FADH2, potential ATP (GTP) and carbon dioxide (does not require oxygen)
occurs in the mitochondria

Question 11

beta oxidation

Answer 11

oxidation of fatty acids to produce ATP; when acetyl-CoA enters the citric acid cycle (fatty acids broken down to produce energy)

Question 12

ketosis

Answer 12

metabolic state that occurs when the body burns fat for energy instead of glucose (because there is not a lot of glucose in the body)

Question 13

amino acid metabolism
