The Glyoxylate Cycle – Definition, Steps, Functions.

The Glyoxylate Cycle: Definition, Steps, Functions.

Glyoxylate cycle Definition Glyoxylate cycle Steps Glyoxylate cycle functions The conversation of dicarboxylic and tricarboxylic acids in germinating seeds occurs in three compartments such as mitochondria, glyoxysomes, and cytosol. During the conversation, the oxaloacetate from the TCA cycle (mitochondria) enters into the glyoxysomes in the form of aspartate. After that, the aspartate converted into oxaloacetate … Read more

Post-glycolysis processes

Post-glycolysis processes

Post-glycolysis processes Glycolysis is a process that involves: Glucose + 2 NAD+ + 2 ADP + 2 Pi → 2 pyruvate + 2 NADH + 2 H+ + 2 ATP Glycolysis could not continue indefinitely if all NAD+ was used up and glycolysis would cease. Organisms must be capable of oxidizing NADH back into NAD+ … Read more

Regulation of Glycolysis

Regulation of Glycolysis

Glycolysis is the primary stage in the process of breaking down glucose in order to obtain energy to power the cell’s metabolism. The majority of living organisms perform glycolysis as a part in their metabolic process. This process does not require oxygen, which is why it is considered anaerobic. Glycolysis happens in the cytoplasms of … Read more

Fates of Pyruvate

Fates of Pyruvate

Pyruvate is a component of the process of lactic acid and alcohol fermentation in anaerobic conditions. in an aerobic state, pyruvate loses carbon dioxide and hydrogen, and transform into Acetyl CoA and enter the TCA cycle. It can as well, enter the biosynthetic pathways. If there is a drop in levels of glucose, pyruvate goes … Read more

Feeder Pathways for Glycolysis

Feeder Pathways for Glycolysis

Numerous carbohydrates, including glucose, meet their catabolic end in Gycolysis after being transformed into glycolytic intermediates. Most significant are glycogen and starch, which are storage polysaccharides that are either in cell walls (endogenous) or in the diet. The disaccharides are maltose. Lactose, trehalose. and sucrose, and the monosaccharides fructose and mannose and galactose. Dietary Polysaccharides … Read more
