Where does this reaction occur?
Cytoplasm of cells/ sarcoplasm of muscles
1 of 16
Why do the first reactions of glycolysis need an input of energy from ATP to get things started?
It is quite stable and unreactive
2 of 16
Where are stores of glycogen kept in the body for the glycolysis?
Liver and muscle cells
3 of 16
What is the main respiratory substrate?
Glucose
4 of 16
How many carbon atoms does a hexose sugar contain?
6
5 of 16
What increases the reactivity of the glucose?
Two phosphate added to the glucose from two ATP molecules
6 of 16
Glucose is split into?
two molecules of 3-carbon (3C) compounds.
7 of 16
Fill in the blank: 'Each intermediate 3C sugar is.............producing a 3-carbon compound, pyruvate'?
oxidised
8 of 16
How many hydrogen atoms are removed are removed during the reaction?
2
9 of 16
What does NAD stand for?
nicotinamide adenine dinucleotide
10 of 16
Is glucose at a higher or lower energy level than the pyruvate?
higher
11 of 16
....on conversion this mean that some energy becomes available for:
the direct creation of ATP
12 of 16
Phosphate from the intermediate compound is transferred to ADP; creating ATP. This is called substrate-level phosporylation?
True
13 of 16
How many ATP molecules are gained from glycolysis?
2
14 of 16
A net gain of two molecules of 3-carbon pyruvate is yeilded by glycolysis?
True
15 of 16
The glycolysis reaction takes place under which conditions?
both
