Metabolic Pathways |
Series of chemical reactions that occur as a part of a process. |
|
Aerobic |
Uses oxygen in cellular respiration |
|
Anaerobic |
Use something besides oxygen in cellular respiration |
|
Cellular Respiration |
- The process by which cells obtain energy from organic molecules |
|
What is a redox reaction? |
- Where oxidation and reduction reaction occurs at the same time |
|
What is NAD |
A co enzyme that can accept or donate a electron |
|
If a chemical reaction releases an electron, Then what are the products? |
The products are reduced because they gained an electron form the reactants. |
|
How do catabolic reactions make ATP? (2 ways) |
1. Substrate level phosphorylation 2. Chemiosmosis |
|
What are the 2 purposes of a catabolic reaction? |
1. To recycle organic building blocks 2. To produce energy intermediates -ATP -Reduced coenzymes |
|
Glycolysis Overview & where it takes place? |
- Involves the breakdown of glucose into Pyruvates -Generates ATP & NADH -Takes place in cytosol -Requires enzymes -Can occur with or without oxygen |
|
3 phases of glycolysis |
1. Energy Investment 2. Cleavage 3. Energy Liberation |
|
Phase 1 Energy Investment |
- 2 ATP molecules are hydrolyzed & the phosphate groups from ATP are attached to the 6-carbon molecule. |
|
Phase 2: Cleavage |
- The 6 carbon molecule is split into 2 (3) carbon molecules. Which is called glyceraldehyde -3 |
|
What is the primary starting food molecule used in cellular respiration? |
Glucose |
|
Phase 3 : Liberation |
Glycealhyde - 3 phosphate molecules are going to be oxidized (losing electrons) which reduces 2 NAD ----> NADH - Net gain is 2 ATP molecules |
