5.6 Respiration Flashcards
1
Q
Why is ATP useful?
A
- Energy is released in small, usable amounts.
- Soluble
- Involves a single step reaction to release energy.
2
Q
What is the word equation for respiration?
A
Oxygen + glucose -> carbon dioxide + water + ATP.
3
Q
What is the symbol equation for respiration?
A
6O2 + C6H12O6 -> 6CO2 + 6H2O.
4
Q
What are the four stages of respiration?
A
- Glycolysis
- Link reaction
- Krebs Cycle
- Electron Transport Chain
5
Q
Define substrate level phosphorylation.
A
- ATP generated directly through respiration.
6
Q
Where does substrate level phosphorylation take place?
A
- Glycolysis and Krebs Cycle.
7
Q
Define oxidative phosphorylation.
A
- ATP generated from the chemical energy released when a coenzyme has been reduced.
8
Q
Where does oxidative phosphorylation occur?
A
- ETC.
9
Q
Why do organisms need ATP?
A
- Protein synthesis
- Active Transport
- Cell maintenance, repair and division.
10
Q
What is the importance of cytochrome c?
A
- Amino acid sequence used to classify organisms.
11
