Cards

Term
anabolic
Definition

uses energy stored in ATP to synthesize  and assemble sub units

small to big

Term
catabolic
Definition

produces energy

big to small

Term
enzyme
Definition

lowers the activation energy of a rxn

its a protein that functions as a catalyst

speeds up rxn

facilitates each step in the metabolic pathway

accelerates the conversion of a substrate to a product

Term
Temp regulation of an enzyme
Definition

increased temp increases the speed of the rxn

extremely high temp makes enzyme non-functional

 

Term
pH regulation for enzyme
Definition

most enzymes work best at a pH slightly over 7

slightly basic

Term
competitive inhibition of enzymes
Definition

competeing for active site with substrate

structually similar to substrate

example: sulfa drugs compete with PABA on enzyme that produce folic acid

Term
non-competitive inhibition of enzymes
Definition

inhibitor and substrate work on different enzyme sites

 

Term
Allosteric inhibition
Definition

non competitive inhibition

alters configuration of the enzymes active site and subtrate wont fit and enzyme is not active

Term
Structure and function of ATP
Definition

Adrenosine triphosphate

molecule of energy

main energy carrier in cells

can give up phosphate group to another molecule and transfer energy

couples energys imputs and outputs

Term
Aerobic metabolic pathway of glucose
Definition

1) glycolysis

2) TCA cycle

3) respiration

Term
glycolysis
Definition
product is pyruvic acid and NADH  and 2 ATP
Term
TCA cycle
Definition
the products are carbon dioxide NADH FADH2 2 ATP
Term
Respiration
Definition
product is 34 ATP and water
Term
fermantation
Definition

usually occurs when there is a lack of oxygenor lack of electron transportation chains

ATP is only produced in glycolysis; only 2
