Answer 1

1. Where does each reaction take place? -

Glycolysis- cytoplasm of a cell

Fermentation- cytoplasm

Acetyl CoA formation- matrix of mitochondria

Krebs Cycle- matrix of mitochondria

ETC - mitochondrial membrane

2. What goes in/comes out of each reaction/name of each reaction? -

Glycolysis - Glucose to Pyruvate

Fermentation - Glucose to Ethanol

Acetyl CoA formation - pyruvate +CoA to Acetyl CoA +CO₂

Krebs Cycle - Acetyl CoA to Malate

3. What are the electron carriers? Where are the electrons actually located?

It is defined as molecules that are capable of accepting one or two electrons from one molecule and donating it to another in the process of electron transport. electrons are not located anywhere they are always in dynamic motion.

4. What are the energy-carrying molecules? Where is the energy actually located?

The energy-carrying molecule is ATP. they are produced by ATP synthase. and it is stored in muscle cells.
