Biol 2051 Microbiology Exam 3

Front 1

Two types of metabolism

Back 1

Catabolism
Anabolism

Front 2

Catabolism

Back 2

breaking down of molecules for energy

Catabolic pathways breakdown large molecules in a series of steps coupled to reactions that store energy in small carriers such as ATP and NADH

Front 3

anabolism

Back 3

process where organisms use energy to build cell components

Front 4

Metabolism

Back 4

balance b/w catabolism and anabolism

Front 5

Examples of catabolic pathways

Back 5

glycolysis: glucose --> pyruvate
and citric acid cycle (TCA)

Front 6

Examples of anabolic pathways

Back 6

pyrimidines - amino acids for making proteins
(smaller molecules to build larger ones)

Front 7

Catalysis

Back 7

change in speed of a chemical reaction due to a catalyst

Front 8

Activation energy

Back 8

energy required to bring all molecules in a chemical reaction to a reactive state

Front 9

Enzymes

Back 9

catalytic proteins that speed up rate of reaction

lower activation energy by bringing substrates into proximity of each other and correctly orienting them

Front 10

Active catalytic site

Back 10

part of an enzyme where the substrate binds

Front 11

Fructose-1,6-bisphosphate with aldolase enzyme yields...

Back 11

glyceraldehyde-3- phosphate + dihydroxyacetone phosphate


aldolase enzyme (at arrow)
Fructose-1,6-bisphosphate → glyceraldehyde-3- phosphate + dihydroxyacetone phosphate

Front 12

T/F
Enzymes can have multiple substrates of multiple shapes bind to them

Back 12

False;
they are very specific
