Photosynthesis and Cellular Respiration Study Guide

Chemical Reaction.
The process of photosynthesis.
Photosynthesis
The most important chemical reaction on our planet.
6CO2 + 6H2O ->C6H12O6 + 6O2
Equation for the Chemical Reaction of Photosynthesis (symbol)
Carbon Dioxide + Water -> Glucose + Oxygen
Equation for the Chemical Reaction of Photosynthesis (words)
Equation for the Chemical Reaction of Photosynthesis
Six molecules of carbon dioxide react with six molecules of water to form 1 molecule of glucose and six molecules of oxygen.
Photosynthesis
The process of changing light energy to chemical energy.
Photosynthesis
Occurs in plants and some algae .
Photosynthesis
Plants need light energy, CO2, and H2O .
Photosynthesis
Takes place in the chloroplasts, using chlorophyll.
Photosynthesis
Plants capture light energy and use that energy to make glucose.
Photosynthesis
Sunlight provides the energy needed by chlorophyll to change molecules of carbon dioxide and water into glucose.
Photosynthesis
Oxygen is released in this reaction.
Photosynthesis
Carbon dioxide enters the leaf through holes called stomata.
Photosynthesis
CO2 combines with the stored energy in the chloroplasts through a chemical reaction to make glucose.
Photosynthesis
The sugar is moved through tubes in the leaf to the roots, stems and fruits of the plants.
Photosynthesis
Some of the sugar is used right away by the plant for energy; some is stored as starch; and some is built into plant tissue
Importance of Photosynthesis to Humans
We cannot make our own food (glucose, energy), we must get our food from plants.
Plants
The first step in the food chain.
Oxygen
Released during photosynthesis; is necessary for all living things.
Cellular Respiration
The release of chemical energy for use by cells.
Cellular Respiration
Once the energy that was in sunlight is changed into chemical energy by photosynthesis, an organism has to transform the chemical energy into a a form that can be used by the organism.
Cellular Respiration
The breakdown of glucose molecules to release energy.
Cellular Respiration
Takes place in all living things.
Cellular Respiration
Is a step by step process.
Glucose + Oxygen -> Carbon Dioxide + Water
Chemical equation for cellular respiration. (words)
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP
Chemical equation for cellular respiration. (symbol)
Cellular Respiration
Glucose to ATP.
