Homework Answers
Oxidative phosphorylation occurs in
the mitochondria.
Glucose is oxidized to produce NADH and FADH2 which are used as
electron donors.
Molecular oxygen is used as the electron acceptor.
During the electron transport, protons are pumped from the matrix into the intermembrane space generating the proton gradient. this proton gradient is coupled to ATP synthesis by the ATP synthase complex.
There are two forms of energy
produced during oxidative phosphorylation:
1. Chemical energy in the form of ATP
It is used for all the anabolic reactions in the cell
2. Heat energy
It is used to maintain body temperature

Inhibitors of Oxidative Phosphorylation The following chemicals inhibit oxidative phosphorylation: Cyanide: Cyanide is a naturally occurring compound that binds to protein complex IV of the mitochondrial electron transport chain and prevents transfer of electrons from the protein. Metformin: At the cellular level, chemically synthesized metformin, a drug commonly prescribed for Type 2 diabetes, inhibits mitochondrial respiration by blocking complex I. Dinitrophenol: Dinitrophenol is a metabolic poison that can be sold legally as a pesticide. Although it is lethal to humans,...

Cellular respiration results in the release of energy from glucose. What is this released energy most often used for?
Question 4 Cellular respiration results in the release of energy from glucose. What is this released energy most often used for? The energy is used to break down fatty acids and triglycerides The energy is used to concentrate water molecules within the cell The energy is used for ATP hydrolysis. The energy is used to form a bond between ADP and Pi The energy is used to produce carbon dioxide and oxygenQuestion 5 During the process of cellular respiration, the majority of the chemical energy that is...

certain drugs are commonly used to study mitochondrial respiration. These drugs include Rotenone, oligomycin, and the mitochondrial uncoupler dinitrophenol. Rotenone inhibits the transfer of electrons from Complex 1 to Uniquinone, oligomycin inhibits Complex 5/ATP synthase by preventing the re-entry of protons into the matrix, and Dinitrophenol leads to the uncoupling of oxidation from phosphorylation of ADP (meaning that less ATP is produced). If you were interested in studying the ATP production through glycolysis only, which of these inhibitors would be...

This is a Biology lab about cellular respiration using
mitochondrial suspension. Here's what my hypothesis is: An
increased amount of the substrate succinate will increase the rate
of cellular respiration.
I was sure that succinate would increase the rate of the
reaction. But that was not what my graph showed. Here is what was
