Yes, RuBisCO is present in C4 plants. Ribulose-1,5-bisphosphate carboxylase/oxygenase or RuBisCO catalyses the first step of carbon fixation in... View Article
Alcoholic fermentation is a process of anaerobic respiration whereby sugar is converted into ethanol and CO2 is released. It is utilised in the... View Article
During oxidative phosphorylation, ATP synthesis is coupled with the transfer of electrons from NADH and FADH2 to O2 by a series of electron... View Article
The citric acid cycle occurs in the mitochondrial matrix. The citric acid cycle or TCA cycle (Tricarboxylic acid) or Krebs cycle starts with the... View Article
During lactic acid fermentation, pyruvic acid is reduced to lactic acid by lactate dehydrogenase in absence of oxygen. NADH is oxidised to NAD+... View Article
There are three major pathways, which can utilise the pyruvic acid produced by glycolysis in the body. They are aerobic respiration and alcoholic... View Article
Oxidative phosphorylation is the main step in aerobic respiration, which accounts for most of the ATPs generated in aerobic respiration. During... View Article
Q is ubiquinone (UQ) in the ETC. It connects complex I and complex II to complex III. The reduced ubiquinone or ubiquinol (QH2 or UQH2) transfer... View Article
No, opuntia performs photosynthesis through the CAM pathway, i.e. crassulacean acid metabolism. It is a carbon fixation pathway adapted by plants... View Article
The main function of the electron transport chain is to generate an electrochemical gradient, which drives the synthesis of ATP during cellular... View Article
Glycolysis is a ten-step process, out of which 7 steps are reversible and 3 steps are effectively irreversible. These are 1st, 3rd and last steps... View Article
Oxidative phosphorylation occurs in mitochondria during cellular respiration. It is called oxidative phosphorylation because the energy of... View Article
Yes, ketone bodies are synthesised from acetyl CoA. Ketone bodies are acetoacetate, β-hydroxybutyrate and acetone. They are formed by the... View Article
Electron transport chain is an aerobic process as oxygen is required in the process. Oxygen acts as a terminal electron acceptor. Also Check:... View Article
Oxygen acts as a terminal electron acceptor in the electron transport chain. It drives the process of hydrogen removal and accepts hydrogen to... View Article
Yes, pyruvate can be converted to glucose, e.g. in gluconeogenesis. Most of the steps of glycolysis are reversible, but three reactions are... View Article
FAD or flavin adenine dinucleotide is a coenzyme and takes part in various redox reactions occurring in the living system. It is involved in... View Article
Glycolysis is the first step in cellular respiration. In glycolysis, glucose is partially oxidised to two molecules of pyruvate. Glycolysis... View Article
