Chapter 6 - Cells At Work Flashcards
1
Q
What is the equation for cellular respiration?
A
C6H12O6 + 6O2 —–> 6CO2 + 6H2O + energy (ATP)
2
Q
What happens in anaerobic respiration?
A
- glycolysis
- 1 glucose molecule breaks down into 2 ATP molecules and 2 pyruvic acid molecules
- if oxygen is unavailable the pyruvic acid molecules are converted into 2 lactic acid molecules
3
Q
What happens to lactic acid after anaerobic respiration?
A
It gets taken to the liver by the blood where it is recombined with oxygen to form glucose.
4
Q
What are the steps of aerobic respiration?
A
Kerbs cycle and electron transport system
5
Q
What happens in the Krebs cycle?
A
- 2 molecules of pyruvic acid are converted into two molecules of ATP
6
Q
What happens in the electron transport system?
A
- remaining glucose is converted into 34 molecules of ATP and water and carbon dioxide
7
Q
Where does glycolysis occur?
A
- cytoplasm
8
Q
Where does aerobic respiration occur?
A
Mitochondria
9
Q
What are some factors that effect enzymes?
A
- concentration of enzymes
- concentration of substrate
- temperature
- pH
