Photosynthesis And Cellular Respiration Essay

Slide #1
Hello, my name is Audrey and welcome to my presentation on the chemistry of photosynthesis and cellular respiration.
Slide #2
To begin, both systems are considered interdependent, which means that one is dependent on the other. You can’t have photosynthesis without cellular respiration and vice versa. Basically, they are two sides to the same coin
Slide #3
The first side of the proverbial coin is photosynthesis. Photosynthesis is an endergonic reaction, meaning that plants absorb light energy, in order to turn carbon dioxide and water into chemical energy.
Slide #4
The very word, photo “synthesis” gives away what kind of reaction it is…a synthesis reaction. In this case, you have two products ( ) in the presence of light energy …show more content…

Once our digestive system has done its thing, breaking larger down into smaller particles, the resulting [products] are carried to our cells by our circulatory system to our tiny cells where cellular respiration happens.
Slide #8
Unlike photosynthesis, cellular respiration is an exergonic reaction where energy is released, rather than absorbed. This released energy is called ATP, the energy currency of the cell.
Slide #9
Also, unlike photosynthesis, cellular respiration is known as a decomposition reaction. During this reaction, the exergonic release of energy is produced by breaking glucose down into smaller ATP molecules, water and carbon dioxide which is released into the air, for use by plants, every time we exhale
Slide #10
Like Photosynthesis, cellular respiration is also a redox reaction where glucose loses electrons and hydrogen atoms to produce carbon dioxide causing the glucose to become oxidized. At the same time, oxygen gains electrons and hydrogen atoms, reducing it to water.
