Hint: The inner mitochondrial membrane (IMM)is the part of theLamellae.It forms the invaginations (cavity) called Cristae. The Mitochondrial Matrix is surrounded by this membrane. The main function of this membrane is to convert the energy.

Complete Answer:
- Glycolysis is the process by which a molecule of glucose gets converted into two molecules of pyruvate, two molecules of water and two hydrogen ions respectively. It takes place in the cytoplasm of eukaryotic cells.
- When organic substrates produce chemical change through the action of enzymes, the metabolic process is called fermentation. It also takes place in the cytoplasm.
- The chains of chemical reactions used by the aerobic organisms to liberate stored energy through the oxidation of Acetyl-CoA are called Krebs cycle. It takes place in the matrix of mitochondria.
- The process of combining carbon dioxide and water in the presence of sunlight and chlorophyll as a catalyst to obtain glucose and oxygen gas is called photosynthesis. It does not take place in the mitochondria.
- The inner mitochondrial membrane which forms the folds known as cristae is the place where ATP synthesis and the transport of electrons take place. Hence, we can say that the inner mitochondrial membrane is the site for the Electron Transport Chain.

Note: The Cristae are the inner membranes in mitochondria. They appear to be highly folded in structure. This is because it allows a much greater amount of electron transport chain enzymes and ATP synthesis to be packed into the mitochondrion.
