Photosynthesis

And Cellular Respiration

By Dail Kang and Nathaniel Leach

Photosynthesis

Plants use roots to collect water or H2O and brings it to the stem so that the water can be brought to the leaves . The leaves are where the glucose or C6H12O6 is made through photosynthesis. The leaves also need to take in CO2 and and they collect this through the stomata. The leaves capture the sunlight to be used as energy. Once the chloroplast has all the materials photosynthesis can occur. The light is converted into ATP. The ATP is used to break down water into hydrogen and oxygen. These materials can then be turned into glucose and oxygen.

Photosynthesis Formula

6CO2+6H2O+sunlight=6O2+ C6H12O6

Cellular Respiration

Cellular respiration is the opposite of photosynthesis. The sugar glucose is broken down to supply energy. The small intestines help separate from the glucose from food and it is sent to the bloodstream so it can then go to the cells. The lungs also take in oxygen, or O2 and release CO2. Once the cells have the glucose aerobic respiration can begin. The glucose enters the cell membrane. It then goes through glycosis. After glycosis, 2 ATP is released and the left over pyruvates enter the mitochondria to be broken down. The pyruvates then move into the mitochondria where they go through Kreb's cycle. After Kreb's cycle CO2 and 32 ATP are released.

Aerobic cellular respiration

O2+C6H12O6-> 6CO2+6H2O+ energy

Photosynthesis and Cellular Respiration

Photosynthesis uses the chloroplast to facilitate the process while cellular respiration uses the mitochondria. Both make ATP and use electron transport chains. They also are used to convert energy. Without photosynthesis plants would not be able to survive because they would not have any means to make energy and sugar. Cellular respiration changes sugar into energy. Without cellular respiration animals would either die or use aerobic cellular respiration but is not an efficient alternative method.
