1. trace the pathway of electrons from glucose through aerobic cellular respiration (all parts) and describe all important events where energy is transferred from one molecule to another.

Explanation:

(1). REDUCTION-OXIDATION REACTION:

Energy is derived from electrons in glucose or glucose metabolites.

(2). MAIN REACTION:

Which is the reaction below;

NAD^+1 + 2 NADH + H^+)

In the equation above Glycolysis provides electrons through 2 NADH which is The hormone insulin signals to the cell's plasma membrane to transport, glucose into the cell, Glycolysis means the breakdown of the glucose molecule.The process breaks glucose down into 2 molecules of Pyruvate, Pyruvate is the ionized form of pyruvic acid, Each molecule of pyruvate contains 3 carbons.

(3). KREBS : provision of electrons through 6 NADH and 2 FADH2. The main aim here is to use the pyruvates to produce more ATP. Oxygen plays an important role here.

Water is the by- product.

Electrons power the proteins and the remaining energy from the glucose is released by the electron transport chain.
