Metabolism

Question 1

Spontaneous Reaction

Answer 1

Continue by themselves once it has started; energy is released -G

Question 2

Nonspontaneous Reaction

Answer 2

Reactions will not take place until something starts them and keeps them going; requires energy +G

Question 3

Nonspontaneous reactions can be paired with ____ reactions in metabolic pathways

Answer 3

Spontaneous

Question 4

Coupled reactions

Answer 4

Spontaneous reaction provides energy needed by the nonspontaneous one; common paired nonspontaneous reaction is formation of ATP(ADP)

Question 5

Metabolism

Answer 5

Sum of all reactions that take place in a living thing

Question 6

Catabolism

Answer 6

Compounds broken down; Energy released

Question 7

Anabolism

Answer 7

Biosynthesis of larger compounds from smaller ones; Energy required

Question 8

ATP ADP energy stored in

Answer 8

Phosphate bond

Question 9

Energy produced in catabolism can be used to produce

Answer 9

ATP

Question 10

Catabolism begins with

Answer 10

digestion

Question 11

Monosaccharides enter

Answer 11

Glycolysis

Question 12

Monosaccharides in Glycolysis produce

Answer 12

NADP, ATP, conversion of one hexose molecule into 2 3-carbon Pyruvates, Pyruvate is modified to Acetyl-CoA, Acetyl CoA enters the citric acid cycle; occurs in cytoplasm

Question 13

Citric Acid Cycle

Answer 13

Cyclic Pathway that produces GTP and reduced coenzymes

Question 14

Fatty Acids undergo

Answer 14

oxidation

Question 15

Fatty acids undergoing oxidation

Answer 15

Produce NADH, FADH2, shorten 2 carbons at a time releasing acetyl-CoA, lose their amino group

Question 16

NADH and FADH2 can enter the

Answer 16

Electron Transport Chain

Question 17

The Electron Transport Chain

Answer 17

Coenzymes are recycled to their oxidative forms, energy released is used during oxidative phosphorylation to produce ATP

Question 18

Occur in mitochondria

Answer 18

Fatty oxidation, amino catabolism, the electron transport chain and oxidative phosphorylation
