Photosynthesis: The process by which light energy is converted into chemical energy

Energy: The ability to do work

3 steps

ATP

Step 2

Step 3

Step 1

Energy is captured from sunlight

Light energy is converted to chemical energy stored as ATP and NADPH

ATP and NADPH powers the formation of organic compounds using carbon dioxide

How it works

Functions

Protein synthesis

Muscle contraction

Active transport across cell membranes

Energy is released when the chemical bond is broken between the 2nd and 3rd phosphate

Calvin Cycle

3 stages

Reduction phase

Regeneration

Carbon Fixation

Factors affecting photosynthesis

Water

Shortage of water can slow or even stop photosynthesis

Temperature

Photosynthesis depends on enzymes who function best between 0ºC and 38ºC
