Photosynthesis

Reactants: CO2 +H2O+energy

products: O2 +C6H12O6

The first thing that happens in photosynthesis is, energy is captured from sunlight. Then, light energy is converted to chemical energy, which is temporarily stored in ATP. Next is, the chemical energy stored in ATP powers the formation of organic compounds (i.e.sugar), using carbon dioxide (CO2). The innermost part of chloroplasts, called the stroma. Most of the enzymes crucial in the process of photosynthesis are normally set in the stroma and in the thylakoid membranes. The stroma is also involved in the combination of organic molecules from water and carbon dioxide. This stroma function is generally known as either the light independent reactions or the dark reactions. Grana (granum) are stacks of structures called thylakoids, which are little disks of membrane on which the light-dependent reactions of photosynthesis take place.

Cellular resperation

Cellular respiration is the way that cells break down sugar that is eaten or produced and this in turn gives them energy called ATP. The total number of ATP it gets is 36 in aerobic respiration. First the sugar molecule (glucose) enters the cells cytoplasm through facilitated diffusion. Then in the cytoplasm glycolysis breaks it into two pyruvates and two ATP is created. It also releases carbon dioxide. It then goes to the mitochondria and the krebs cycle is activated releasing two ATP and H2O. Then it goes into the electron transport train and 32 ATP is released ending the aerobic respiration with 36 ATP in total. Next is Anaerobic Respiration which instead of going into the mitochondria after glycolysis. It stays in the cytoplasm and only gives you two ATP. Also it give off lactic acid which makes your muscles sore. The Equation is C₆H₁₂O₆ + O₂ → CO₂ + H₂O + energy

Comparison

Cellular respiration takes a glucose molecule and combines it with oxygen and the result is energy in the form of ATP. Photosynthesis takes carbon dioxide and combines it with water, enabled by sun’s energy. The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart.
