Photosynthesis and Cellular Respiration

Cellular Respiration

The process that releases energy (ATP) by breaking down glucose. (converts food molecules (glucose) into a form usable (ATP) by the organism)

ATP (adenosine triphosphate)

Energy. Main energy source that cells use for most of their work.

Mitochondria

Organelle found in all organisms that is the site of cellular respiration

Definition of Cellular Respiration

The process of breaking the chemical bonds of glucose into energy.

Cellular Respiration Chemical Equation

C6H12O2 + 6O2 ------> 6CO2 + 6H20 + Energy (ATP)

Location of Photosynthesis

Chloroplast

Reactants of Photosynthesis

6H20 + 6CO2

Products of Photosynthesis

C6H12O6 + 6O2

Plants need these to survive

Water, carbon dioxide, and light

Animals need these to survive

Food, oxygen, and water

Gas released by plants during photosynthesis

oxygen

autotroph

An organism that makes its own food

heterotroph

An organism that cannot make its own food.

reactants

The starting material in a chemical reaction

chlorophyll

Absorbs light energy.

Pigment that gives a plant its green color. Found in the chloroplast

chloroplast

organelle where photosynthesis takes place.

oxygen

product of photosynthesis

carbon dioxide

Gas taken in and used during photosynthesis.

leaf

the part of the plant where most photosynthesis takes place

light energy

energy from the sun that is used by plants to produce their own food by the process of photosynthesis

Photosynthesis

converting light energy to the chemical energy of food, in plants

Glucose

the type of sugar made during photosynthesis

product

a substance that is formed by a chemical reaction

water formula

H2O

carbon dioxide formula

CO2

glucose formula

C₆H₁₂O₆

oxygen

O2

reactants of cellular respiration

glucose and oxygen

products of cellular respiration

carbon dioxide, water, and ATP

Kreb's Cycle

second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions

Glycolysis

the breakdown of glucose by enzymes, releasing energy and pyruvic acid.

Electron Transport Chain

series of electron carrier proteins that shuttle high-energy electrons during ATP-generating reactions
