Aerobic Respiration - Stage 1/Glycolysis Flashcards
What is stage one of aerobic respiration called?
Glycolysis
Define glycolysis
The conversion of glucose into two molecules of pyruvic acid
Where does glycolysis take place in a cell?
The cytosol of the cell
Does glycolysis require oxygen?
No, it is anaerobic
How many molecules of ATP are formed by glycolysis?
Two molecules of ATP are formed
What is the end product of glycolysis?
Pyruvic acid
What happens to 2 ADP + 2 Pi during glycolysis?
It is converted into 2 ATP + water
What is converted into 2 ATP + water during glycolysis?
2 ADP + 2 P
What is converted to 2 Pyruvic acid (C3) during glycolysis?
Glucose (C6)
What is glucose (C6) converted into during glycolysis?
2 pyruvic acid
What is NAD+ converted into during glycolysis?
NADH
What is converted into NADH during glycolysis?
NAD+
What happens as the glucose is broken down into pyruvic acid?
(2)
NAD+ + 2e- + H+ –> NADH
(Pyruvic acid loses two electrons and a proton which converts NAD+ into NADH)
2ADP + 2P –> 2ATP + water
(Entergy from the breakdown of glucose into pyruvic acid converts 2ADP + 2P into 2ATP + water)
List the end products of glycolysis
4
ATP
Water
NADH
Pyruvic acid
What happens to NADH formed in glycolysis?
It enters the electron transport system
