Photosynthesis

What is photosynthesis?

The process that uses light energy to convert substances into the environment into plant food (glucose).

Create their own food and feed other living things.

Autotroph

Define Heterotroph

Obtain food from other heterotrophs and autotrophs

General formula for photosynthesis?

6 CO2 + 6 H2O = C6H12O6 + 6 O2

Carbon + Water = Glucose + Oxygen

Contains a light-absorbent pigment called chlorophyll?

Thylakoid membrane

Fluid-filled internal space of chloroplasts were the Calvin Cycle takes place?

Stroma

Stacks of Thylakoids are called?

Grana

Requires sunlight and occurs in the thylakoid membrane, what type of reaction is this?

Light Dependent Reaction

It doesn't need sunlight, and occurs in the stroma, what type of reaction is this?

Light Independent Reaction

What replaces electrons used in photosytem ll?

Water

What “excites” electrons in photosystem ll?

Sunlight

What is the name of the final electron receiver for photosynthesis, also known as the electron carrier?

NADPH

The high concentration of hydrogen in the thylakoid causes…

… ATP synthase to rotate creating ATP.

What is the purpose of the Light Dependent Reaction?

To create ATP and NADPH that will be used in the Calvin Cycle. It also creates some oxygen that can be used in Cellular respiration.

List the 3 steps of the Calvin Cycle.

1. Carbon Fixation
2. Reduction
3. Regeneration of RuBP

What is the purpose of the Calvin Cycle?

To create glucose, it will be used in Cellular Respiration.
