Cards

Term
Metabolism
Definition
the sum of all chemical and physical changes that occur in body tissues
Term
Anabolism
Definition
the process of making new molecules from smaller ones
Term
Catabolism
Definition
the breakdown or degradation of larger molecules to smaller molecules
Term
ATP
Definition
ATP, standing for adenosine triphosphate, is a compound of energy that is released during reactions
Term
When does ATP provide energy?
Definition
When bonds between phosphate groups break
Term
What can happen to glucose after it is phosphorylated?
Definition

It can be stored as glycogen

 

or

 

oxidized for immediate energy

Term
What happens during glycolysis?
Definition
Glucose is converted to pyruvate
Term
Net production of glycolysis
Definition

2 pyruvate molecules

2 ATP

2 NADH & H+

Term
What happens to the 2 hydrogen atoms released during glycolysis?
Definition
They are picked up by the coenzyme NAD
Term

What does NAD turn into when it picks up 2 hydrogen atoms?

 

Definition
NADH
Term
What is the anaerobic result of glycolysis?
Definition
Lactate (lactic acid)
Term
How does glycolysis continue through lactic acid?
Definition
The production of lactate allows the regeneration of NAD+
Term
What is the aerobic result of glycolysis?
Definition
acetyl CoA
Term
What is acetyl CoA?
Definition
A two carbon compound
Term
Can acetyl CoA metabolize into glucose?
Definition
No
Term
What are the results of the TCA cycle?
Definition
Carbon dioxide, ATP, NADH and FADH
Term
Can fatty acids be converted to glucose?
Definition
No
Term
What molecule is common to carb, lipid, protein and alcohol metabolism?
Definition
Alcohol dehydrogenase (ADH)
Term
Why can't glucose be formed from fatty acids?
Definition
There is no metabolic pathway to convert actyl CoA into pyruvate for glocose synthesis
Term
What molecule is require for Acetyl CoA to proceed into the TCA cyle?
Definition
Oxaloacetate
