Similarities Between Cellular Respiration And Photosynthesis

What are the similarities and difference between cellular respiration, fermentation, and photosynthesis? Well, cellular respiration is a series of chemical reactions that convert into energy in food molecules into a usable form of energy called ATP. Fermentation is a reaction that eukaryotic and prokaryotic cells can use to obtain energy from food when oxygen levels are low. Photosynthesis is a series of chemical reactions that convert light energy, water, and CO2 into the food-energy molecule glucose and give off oxygen. The similarities are, they all make energy/food to make energy. Also, they either create sugar or use sugar. However, cellular respiration has two steps and the first step has glycolysis that occurs in the cytoplasm of cells. Glycolysis produces ATP molecules and uses energy from other ATP molecules. The second step occurs in the mitochondria of eukaryotic cells and requires oxygen. Then smaller molecules from the glycolysis breakdown and large portions of ATP are produced. Next the cells use ATP to power all

Which absorbs all of the colors except green, that’s why most plants are green. However, plants contain color that reflect other colors such as red and yellow. These reactions occur in chloroplast which are organelles that use light energy and make food called glucose. One of the main difference between photosynthesis, cellular respiration, and fermentation is that photosynthesis uses sunlight.

In conclusion, the similarities are that they all make food or energy and create sugar or use sugar. On the other hand, photosynthesis only happens in a plant cells and both cellular respiration and fermentation happen in animal and plant cells. Cellular respiration is basically the reverse of photosynthesis. Also, fermentation doesn’t need oxygen to make energy. This shows how cellular respiration, fermentation, and photosynthesis are similar and
