ATP And ADP Comparison To Battery
ATP stores large amounts of energy like a fully charge battery. ADP stores a little amount of energy like and almost dead battery.
Why ATP Is The Preferred Energy Source
ATP is the preferred energy source because it stores more energy than ADP.
Photosythesis
Definition of Photosynthesis
Photosynthesis- A chemical reaction that requires the energy of sunlight to covert water and carbon dioxide into glucose and oxygen.

Photosynthesis Paragraph
Photosynthesis is a chemical reaction in which sunlight, water, and carbon dioxide are the reactants in producing oxygen, sugar known as glucose, and ADP. Photosynthesis takes place in the thylakoids and stroma of the chloroplast. The Thylakoids are responsible for the Light Reactions and the stroma are responsible for the Calvin Cycle. Water and light go into the thylakoids to make oxygen. Carbon dioxide goes into the Calvin Cycle to produce glucose and ADP. Only autotrophs experience photosynthesis.
Cellular Respiration
Definition of Cellular Respiration
Cellular Respiration- A chemical reaction that releases energy by breaking down glucose in the presence of oxygen.

Cellular Respiration Parapraph
Cellular respiration is a chemical reaction in which glucose is broken down in the presence of oxygen. This produces water, carbon dioxide, and ATP. Glucose and oxygen are reactants. This process takes place in the mitochondrian. The process taken place within the mitochondrian in which citric acid is produced is known as the Kreb's Cycle. Cellular respiration takes place in all organisms.
