A. True B. False
A. True B. False
A. Malate B. Pyruvate C. Glyoxylate
A. Fructose-6-phosphate B. Glucose-1-phosphate
ANSWER 1. TRUE
Recent studies have indicated that shifts in tissue metabolism result from a combination of profound recruitment of inflammatory cells (neutrophils and monocytes) and high proliferation rates among lymphocyte populations . The resultant shifts in energy supply and demand can result in metabolic acidosis and diminished delivery , availablity of oxygen , leading to hypoxia extensive enough to trigger transcriptional and translation changes in tissue phenotype.
ANSWER 2. FALSE
Cancer cells are shown to experience characteristic changes in their metabolic programs , including increased uptake of glucose , enhanced rates of glutaminolysis and fatty acid synthesis, suggesting metabolic shifts supports tumor cells growth.
ANSWER 3. MALATE
In this instead of direct fixation by RuBisCo into three carbon compound , 3-phosphoglycerate. Carbon dioxide is incorporated into a four carbon organic acid (malate or aspartate)
ANSWER 4. Glucose-1 phosphate
Galactose is converted to galactose 1 phosphate by the action of galactokinase. Galactose - 1 phosphate is converted to glucose 1 phosphate by the action of uridyl transferase enzyme.
