RuBP Carboxylase- This is a part of dark reaction of photosynthesis. It catalyses the fixing of CO2 in C3 cycle.
PEPcase - This is a part of photosynthesis of C4, plants. It catalyses the reaction of fixing of CO2 to form first stable product oxaloacetate. 4 carbon compound.
Pyruvate dehydrogenase - It is involved in aerobic respiration and catalyses the reaction of formation of acetyl Co-A from pyruvic acid. It requires the participation of NAD and Co-enzyme.A.
Pyuvic acid+CO−A+NAD+Mg2+−−−−−−−−−−−−−−→Pyruvate dehydrogenaseAcetyl Co−A+CO2+NADH+H+
ATPase- it is a part of both respiration and photosynthesis. Both these processes uses electron transport chain and associated proton pump and ATP synthase as a key part of process, ETC uses the energy to pump hydrogen ions across a membrane.
The protons flows back through ATP synthase, driving the production of ATP.
Cytochrorne Oxidase -This is involv. in both respiration a. photosynthesis. H is an electron carrier in the electron transport chain.
Hexokinase - This enzyme is also involved in, respiration. In glycolysis, it catalyses the first reaction, Le., formation of gluCose -6- phosphate from glucose molecule, It uses one ATP molecule which transfers PO4 group to glucose molecules.
Lactate Dehydrogenase
This enzyme is involved in anaerobic respiration in bacteria Lactobacillus. Pyruvic acid formed at the end of glycolysis is converted to lactic acid by homo-fermentative lactic acid bacteria. Hydrogen from NADH molecule is transferred to pyruvate is transferred to pyruvate molecule lactic acid molecule leading formation of acid.
