ATP
Adenosine triphosphate. It is made from ADP+Pi.It is the main source of energy for cellular activities.
1 of 15
glycolysis
The first stage of respiration in which glucose is broken down to pyruvic acid
2 of 15
2 ATPs
Net gain in glycolysis
3 of 15
cytoplasm
Where glycolysis and anaerobic respiration takes place
4 of 15
large surface area
The mitchondrion has a double membrane. It is folded which increases the activity of a mitochondrion.
5 of 15
cristae
The folds which are the site of the cytochrome system
6 of 15
matrix
site of the Krebs cycle
7 of 15
citric acid
6C compound made from a 2C-acetyl group which bonds to a 4C in the Krebs cycle
8 of 15
Hydrogen
Gas released during Krebs cycle
9 of 15
reduced co-enzyme
Hydrogen released is picked up by a co-enzyme named NAD to form NADH2
10 of 15
carrier system
Consists of a series of carriers. Hydrogen and electrons are transferred through this. Found in the cytochrome system.
11 of 15
oxygen
final hydrogen acceptor
12 of 15
lactic acid
In oxygen debt pyruvic acid is converted to this.
13 of 15
prolonged exercise
As in a marathon, glucose is constantly absorbed from the blood by the muscles and used in respiration. Glucose is replaced by the release of glucose into the blood from the breakdown of stored glycogen
14 of 15
prolonged starvation
Protein is used as an energy source after the stores of glycogen and fats are used up.
