Module 7- Metabolism Flashcards
Exam 3
Anabolism
- Building body compounds
- Thermodynamically unfavorable
- Requires energy
Thermodynamically unfavorable
Requires a large amount of energy
Catabolism:
- Breaking down body compounds
- Releases energy
- Thermodynamically favorable
Coupled Reaction:
Energy released from breakdown (hydrolysis) of reaction used to fuel second reaction (such as building)
Hydrolysis
breaking apart with water
Thermodynamically favorable
Does not require a lot of energy
Aerobic
requires oxygen
Ketabolism:
process of tissue breakdown that occurs during starvation ketosis
What is anabolism the process of?
process of building complex molecules from simpler ones
What is catabolism?
set of metabolic pathways that breaks down large molecules into smaller units
Is ATP concentration high or low?
SUPER high
Is ADP concentration high or low?
SUPER low
What does ATP turn into?
ADP
Is going from ATP to ADP favorable or unfavorable?
favorable because we always have way more ATP than we need
Glucose must go through what to get into the cell?
It has to through a GLUT transfer or GLUT4
Hexokinase
a coupled reaction, a regulatory step that traps glucose in the cell and turns it into Glucose 6 Phosphate
What does Glucose turn into when it enters the cell?
Glucose 6 Phosphate
What is a regulatory step?
It requires energy
What does the nucleus contain?
DNA
What does Cytosol contain?
- Glycolysis occurs here
- Anaerobic
Mitochondria
- Energy metabolism (“Powerhouse”)
- Electron Transport Chain
- Aerobic
- Krebbs Cycle
What is the Electron Transport Chain?
Oxidated Phosphorylation
What does Oxidated Phosphorylation require?
Oxygen
What stabilizes a phosphate group?
Mg2+, the 2+ stabilizes the Beta and Gamma phosphate. It can shift over though leaving the Gamma exposed causing hydrolysis to occur.
