1.6 Respiration Flashcards
1
Q
What is ATP used for?
A
Cellular activities such as:
* Muscle cell contraction
* Cell division
* Protein synthesis
* Transmission of nerve impulses
2
Q
What is respiration?
A
Respiration is a series of enzyme controlled reactions that release the chemical energy stored in glucose
3
Q
What is the word equation for aerobic respiration?
A
Glucose + oxygen —> carbon dioxide + water + energy
4
Q
What is the first stage of respiration?
A
- Glucose –> 2 pyruvate +2 ATP
- Takes place in the cytoplasm
- Occurrs in all types of respiration in plant, animal, and fungus cells
- Oxygen is not required
5
Q
What is the second stage of aerobic respiration?
A
- 2 pyruvate –> carbon dioxide and water, and lots of ATP
- Takes place in the mitochondria
- Glucose is completely broken down
6
Q
What is fermentation in animals?
A
- Fermentation occurrs when no oxygen is present
- Pyruvate is broken down into lactate
- This yields 2 ATP and is reversible
7
Q
What is fermentation in animals?
A
- Fermentation occurrs when no oxygen is presesnt
- Pyruvate is broken down into alcohol (ethanol) and carbon dioxide
- This yields 2 molecules of ATP and is not reversible
8
Q
What is the word equation for fermentation in animals?
A
Glucose + oxygen —> lactate + energy
9
Q
What is the word equation for fermentation in plants?
A
Glucose + oxygen —> ethanol + carbon dioxide + energy
