Why the phosphorolysis of glycogen is more efficient than the hydrolysis of glycogen in mobilizing glucose for the glycolytic pathway? Explain. Glycogen: Glycogen is referred to as a storage form of glucose; it is an important reserv...
To achieve this, cancer cells must overexpress glucose transporters to import glucose and overexpress enzymes of the glycolytic pathway or encode specific isoforms of these enzymes, as hypothesized by several Conflict of interests None declared.
Describe the mechanism of ATP synthesis. Explain what happens to glycolysis and gluconeogenesis, in an extended fasted state. Include hormones that are involved. Explain how this differs in ruminants. What is the product of glucose in the glycolytic pathway?
Our analysis of healthy human fecal metagenomes from three separate cohorts revealed thousands of genes whose abundance differs significantly and consistently between people, including glycolytic enzymes, lipopolysaccharide biosynthetic genes, and secretion systems. Even housekeeping pathways contain a mix of ...

“Infection triggers expansion and effector differentiation of T cells specific for microbial antigens in association with metabolic reprograming. We found that the glycolytic enzyme lactate dehydrogenase A (LDHA) is induced in CD8+T effector cells through phosphoinositide 3-kinase (PI3K) signaling. ...

Under hypoxic conditions the organism needs more glucose, because it changes from the oxygen consuming pentose phosphate (36ATP/glucose molecule) to the anaerobic glycolytic pathway (2ATP/glucose molecule). Hence insulin, as it promotes the absorption of glucose, is set in the center of interest ...
In the presence of oxygen, the reducing equivalents of NADH are passed into the mitochondria for reoxidation. Under anaerobic conditions, on the other hand, the NAD is replenished by the reduction of pyruvate in an extension of the glycolytic pathway. Two processes for the anaerobic replenishmen...
2. Provide an example of a negative feedback loop in the glycolytic pathway. Describe the structure and function of cadherins. Only birds and mammals can generate urine that is hypertonic to plasma. The foundation of this ability lies in the function of the loop of Henle. Exactly what does...
