Cellular Respiration and PhotosynthesisYou will need to know the inputs and

outputs of each reaction

The overall reaction for Cr and Ps

Where is each reaction taking place

Understand what the “goal” of each reaction is

What is the role of the major molecules

Connect back to previous material (facilitated diffusion, active transport, exergonic, endergonic)

Rs - Equation

C6H12O6 + 6 O2 6 CO2 + 6

H2O + ATP

The energy is released from the chemical

bonds in the complex organic molecules.

Oxidation - definitions

Loss of electrons.

Loss of energy.

Reduction - definitions

Gain of electrons.

Gain of energy.

Photosynthesis Equation

Why do you suffocate when you lose access to oxygen?

a. Explain what happens inside your mitochondria when you lose access to oxygen and why this poses such a dire problem for your cells.

b. How is it that some other organisms don’t suffocate in oxygen-free environments, and in fact thrive there?
