|
Glucose exists in a |
ring formation. therefore having a small chance to modify other proteins |
|
|
glycolysis is an |
energy conversion pathway |
|
|
glycolysis is present in both |
prokaryotic and eukaryotic cells |
|
|
in eukaryotic cells, glycolysis takes place in the |
cytoplasm |
|
|
2 stages of glycolysis |
1) the trapping and preparation stage 2) ATP is harvested |
|
|
Stage 1 of glycolysis |
No ATP is generated in this stage. Begins with the conversion of glucose into fructose. the strategy of the initial steps of glycolysis is to trap the glucose in the cell and form a compound that can be readily cleaved into phophorlated three carbon units |
|
|
The three steps of the conversion from glucose to fructose |
phosphorylation isomerization second phosphorylation reaction |
|
|
What traps glucose in the cell and begins glycolysis |
Hexokinase |
|
|
What is a kinase |
enzymes that catalyze the transfer of a phophoryl from ATP to an acceptor |
|
|
The glycolytic pathway is |
tightly controlled |
|
|
two roles of the glycolytic pathway |
1) degrades glucose to form ATP 2) provides building blocks for biosynthetic reactions |
|
|
Glycolysis in muscle is regulated by |
feedback inhibition to meet the need for ATP |
