Lactic acid bacteria do not produce carbon dioxide. They convert pyruvate to lactate. Also Check: Types Of Fermentation Does Fermentation... View Article
When the oxygen supply is inadequate, cells lack mitochondria or energy requirement is more than the rate of formation of ATP by oxidative... View Article
In the absence of oxygen, fermentation occurs. Pyruvate produced by glycolysis is converted to alcohol or lactic acid during fermentation.... View Article
The citric acid cycle is the aerobic pathway of cellular respiration. Although it doesn’t utilise oxygen directly, the NADH and FADH2 produced in... View Article
There is a net yield of 2ATP molecules in glycolysis. 4 ATPs are produced but 2 ATPs are utilised in the first half. 2NADH is also produced in... View Article
Fermentation is not involved with the electron transport chain. Only 2 ATP molecules are produced, that is during glycolysis. Also Check:... View Article
In terms of the end product yes, during glycolysis glucose is converted to pyruvate and in gluconeogenesis, pyruvate is converted to glucose. But... View Article
The main function of gluconeogenesis is to produce glucose from noncarbohydrate sources such as glucogenic amino acids, glycerol, etc. Also... View Article
Hexokinase acts on hexose sugar and phosphorylates forming hexose phosphate. Glucose is the most common substrate of hexokinase. It catalyses... View Article
Glycolysis produces two molecules of pyruvate after partial oxidation of glucose. There is a net yield of 2 ATP and 2 NADH molecules also.... View Article
Yes, glycogenolysis occurs in muscles. Breakdown of glycogen is an immediate source of energy for muscle contraction as it provides glucose... View Article
Km value is equal to the substrate concentration at which half of the enzyme active sites are saturated with the substrate. It tells about the... View Article
Vmax is the maximum velocity of the reaction for the given concentration of enzyme. An increase in the substrate concentration increases the... View Article
The level of blood glucose is mainly regulated by hormones secreted by the pancreas, i.e. insulin and glucagon. Insulin stimulates glycogenesis,... View Article
The breakdown of glycogen to glucose is called glycogenolysis. Glycogen primarily stored in the liver and muscles is broken down to glucose to... View Article
Yes, hexokinase is found in the cytosol. It catalyses the first step of glycolysis, i.e. glucose is converted to glucose-6-phosphate. Also... View Article
RuBisCO is the most abundant enzyme present in the world. The full form of RuBisCO is Ribulose-1,5-bisphosphate carboxylase oxygenase. It... View Article
The formation of succinyl CoA by α-ketoglutarate is an oxidative decarboxylation. The reaction is catalyzed by α-ketoglutarate dehydrogenase. One... View Article
