. Happens in the presence of Light.
. Occur in the thylakoid membrane of

chloroplast

. Water is split into oxygen gas (O2) and H+

. Use light energy (photons) to generate two

chemical energy compounds: Adenosine
Triphosphate (ATP) & nicotinamide adenine
dinucleotide phosphate (NADPH).

14. Calvin Cycle (Dark Reaction)

1. Light independent (can occur in light or
dark; some enzymes require activation by
light)

2. Occur in the stroma of chloroplasts

3. Use the chemical energy produced in Light
Reactions (ATP; NADPH) to reduce CO2 to
carbohydrate (sugar).

20. CELLULAR
RESPIRATION

21. What is

The release of ee energy for use by
cells.

Process of making energy of food available
in the cell

All organisms need energy to perform
essential life processes.

The food must be digested to simple forms
such as glucose, amino acids, and
triglycerides.

The immediate energy source of the cells
is GLUCOSE.

22. Cellular Respiration:

Cellular respiration is the process by which the energy of
ca is + in the cell to be used for life processes

29. 1. Glycolysis

In glycolysis, the 6-carbon sugar, glucose, is broken down into two
molecules of a 3-carbon molecule called pyruvate. This change is
accompanied by a net gain of 2 ATPmolecules and 2 NADH molecules.

30. 2. Krebs Cycle:

The Krebs Cycle occurs in the mitochondrial matrix
and generates a pool ofchemical energy (ATP, NADH,
and FADH2) from the oxidation of pyruvate, the end
product of glycolysis.

31. 3. Electron Transport System:
also happens in the mitochondria, more ATP
are generated (32).

For each glucose molecule, total ATP = 36.
