RuBPCarboxylase is an enzyme that takes part in dark reaction of photosynthesis. It catalyses the fixing of $\mathrm{CO}_2$ in $\mathrm{C}_3$ cycle. PEPcase an enzymes that takes part in photosynthesis of $\mathrm{C}_4$ plants. It catalyses the reaction of fixing of $\mathrm{CO}_2$ to form first stable product oxaloacetate. 4 carbon compound. Pyruvate dehydrogenase is an enzyme involved in aerobic respiration and catalyses the reaction of formation of acetyle Co-A from pyruvic acid. It requires the participation of NAD and Co-enzyme-A.


ATPase is a part of both respiration and photosynthesis. Both these processes uses etc, associated proton pump and ATP synthase. These all play a key part in the process is used by ETC pump hydrogen ions across a membrane. The protons flows back through ATP synthase, driving the production of ATP.
Cytochrome Oxidase is involved in both respiration and photosynthesis. It acts as electron carrier in the electron transport chain.
Hexokinase is an enzymes which is also involved in, respiration. In glycolysis, it catalyses the first reaction, i.e., formation of glucose -6- phosphate from glucose molecule. It uses one ATP molecule which transfers $\mathrm{PO}_4$ group to glucose molecules.

Lactate Dehydrogenase is an enzyme which is involved in anaerobic respiration in bacteria Lactobacillus.
Pyruvic acid formed at the end of glycolysis is converted to lactic acid by the help of homo-fermentative lactic acid bacteria. Hydrogen from NADH molecule is transferred to pyruvate is then transferred to pyruvate molecule lactic acid molecule leading to the formation of acid.
