what is lactate
Process that generates most of the NADH that delivers electrons to the electron transport chain?
what is critic acid cycle
Based on question 11's diagram on quiz handout (I can't upload pics)
The diagram shows possible pathways for the breakdown of glucose in various cells.
1. The names of substances A and D?
2. The names of process C and R and role of glycolysis in both processes.
1. what are A-pyruvate and D- CO2
2. what are Q-fermentation and R-aerobic respiration.
Glycolysis is a required and integral process of both fermentation and aerobic respiration. The pyruvate generated from glycolysis is required for the two pathways.

A researcher studies the effect of an enzyme solution. After addition of she observes that pyruvate and NADH are produced.
Can ATP be produced through the activity of the enzyme solution?
Can this enzyme solution play a part in anaerobic catalysis of glucose?
What is yes.
Yes: ATP can be produced through the activity of the enzyme solution
Yes: enzyme can play a role in anaerobic breakdown
NADH and NADPH are major coenzymes for oxidoreductases. While nearly equivalent in redox potential, the two coenzymes often function in different metabolic actions. In general:
NADH is often involved in degradation and NADPH in synthesis
The overall steps of the Electron Transport Chain in animal cells?
NADH and FADH2 are oxidized, hydrogen ions move into the intermembrane space, ATP is generated.
In animals, fatty acids are produced from excess carbohydrates in the liver and adipose (fat) cells by the FASI protein complex (fatty acid synthase I). FASI covalently attaches acetyl CoA into long chains with a terminal carboxyl group.
The number of molecules of acetyl CoA does the synthesis of the fatty acid stearic acid require is...

In chemiosmosis, what is the most direct source of energy that is used to convert ADP + to ATP?
energy released from movement of protons through ATP synthase, down their electrochemical gradient
