Cards

Term
2 categories of metabolism
Definition

Catabolism - ATP Production, Glycolysis and the TCA Cycle

Anabolism - Synthetic pathways, protein synthesis

Term
Metabolsim?
Definition
All chemical reactions that take place within an organism
Term
Metabolic pathways
Definition
network of linked reactions
Term
Basic feature of metabolism
Definition
coupling exergonic reactions with endergonic reactions
Term
Energy?
Definition
the capacity to do work
Term
Enzyme
Definition

biological catalyst

lowers activation energy

 

Term
Energy released in catabolic reactions is trapped in?
Definition

phosphate bonds

electrons

Term
Enzyme modulators
Definition

feedback or end product inhibition

hormones

other signaling molecules

Term
2 types of catabolic pathways
Definition

Anerobic pathway

Aerobic pathway

Term
Characteristics of Glycolysis
Definition

1 glucose produces 2 pyruvate molecules

main catabolic pathway of cytoplasm

does not require O2 

phosphorylation of glucose to glucose 6-P

Term
Pyruvate in Anerobic catabolism turns into?
Definition
Lactate
Term
Pyruvate in Aerobic catabolism turns into?
Definition
Citric Acid Cycle
Term
Mitochondrial metabolism is blocked without?
Definition
oxygen
Term
Waste  product of Citric Acid Cycle?
Definition
2 CO2
Term
Energy produced in the citric acid cycle
Definition

1 ATP

3 NADH

1 FADH2

Term
Chemiosmotic theory
Definition
movement of electrons through the ETC to produce ATP
Term
Cytochrome
Definition
iron-containing protein
Term
ETC occurs in?
Definition
the inner membrane of the mitochondira
Term
Oxidative phosphorylation
Definition
oxygen is required as the final electron and proton acceptor
Term
ATPsynthase
Definition

protons move back to the mitochondrial matrix 

stored energy is converted to chemical bond energy

ATPsynthase transfers KE to ATP

some energy is released as heat and absorbed into the blood

Term
Lipase
Definition
breaks lipids into glycerol
Term
Beta oxidation
Definition
glycerol enters the glycolytic pathway
