1
New cards
What is the key function of metabolism according to the lecture?
To generate chemical energy (ATP), transport electrons (NADH and NADPH), and synthesize macromolecules needed for cell growth and survival.
2
New cards
What happens during glycolysis?
Glucose is converted into pyruvate, producing ATP and NADH as energy currencies.
3
New cards
Which enzyme phosphorylates glucose in the glycolysis pathway?
Hexokinase (HK) phosphorylates glucose.
4
New cards
What are the two main phases of glycolysis?
The Investment/Preparatory Phase and the Payoff Phase.
5
New cards
What is the net production of ATP from one molecule of glucose during glycolysis?
2 ATP.
6
New cards
What is the role of Phosphofructokinase (PFK) in glycolysis?
It phosphorylates Fructose-6-phosphate to Fructose-1,6-bisphosphate.
7
New cards
What is produced at step 10 of glycolysis?
Pyruvate.
8
New cards
What does NAD+ become when it is reduced?
NADH.
9
New cards
Which reaction type occurs in the step where Glyceraldehyde 3-phosphate (G3P) is oxidized?
An electron transfer reaction.
10
New cards
Which enzymes are responsible for isomerization in the glycolysis pathway?
Phosphohexose isomerase and Triose phosphate isomerase (TIM).
