Photosynthesis and Cellular Respiration

Cellular processes

Cornell Notes #8

What is Cellular Respiration?

• Transforms unusable energy from food molecules into usable energy for the cell

• Produces ATP

• Uses oxygen

• Occurs in mitochondria

CR inside mitochondria

Glucose + Oxygen Carbon dioxide + Energy

What cells use cellular respiration?

• Most cells

What is Fermentation?

• Process to produce energy (ATP) without the use of oxygen.

• Two types

• Lactic acid fermentation - produces lactic acid and carbon dioxide

• Alcohol fermentation - produces ethanol

Fermentation

Lactic acid fermentation

Alcohol fermentation

What is Photosynthesis?

• Using the sun’s energy to make food

• Requires a pigment called chlorophyll

• Occurs inside chloroplasts

Photosynthesis

Carbon dioxide + Water Glucose + Oxygen

What cells use Photosynthesis?

• Plant cells
