Answer:
Retinoblastoma is more common in people due to the mutation of RB gene in them.
Explanation:
Retinoblastoma is a disease that affects the eyes of an individual. It is more commonly eye cancer which occurs on the retina of the eye. Retinoblastoma mainly affects younger children.
When the RB gene is mutated or it is deleted already on any one of a homologous chromosomes, then only one hit rather that two which is needed to cause the development of retinoblastoma and hence the probability is of retinoblastoma to occur is higher in the individuals who have already inherited the RB deletion and also have a genetic predisposition for the retinoblastoma.

The suppression of glycolysis is responsible for a large portion of the control of gluconeogenesis.
Discussion about the statement:
The cytosol is the site of all glycolysis and gluconeogenesis processes. The rate at which glucose is produced in the body is inversely related to the intake of carbohydrates. The suppression of glycolysis is responsible for a large portion of the control of gluconeogenesis.
Fructose 2,6-bisphosphate is an intermediate that plays a crucial role in controlling both glycolysis and gluconeogenesis. This metabolite's presence can promote glycolysis and prevent gluconeogenesis.
Control of Gluconeogenesis and Glycolysis
- At various crucial stages of glycolysis and gluconeogenesis, metabolic control takes place. The catalysts that accelerate each of these stages can be activated or inhibited by outside forces, for example, the quantity of a molecule that comes after. The conversion of glucose and ATP into glucose 6-phosphate is the first controlled step in glycolysis. Keep in mind that hexokinase catalyzes this process.
- High levels of blood glucose, AMP, and low levels of cellular ATP all trigger the activation of hexokinase. In other words, the glycolysis process is enhanced when blood glucose levels are high. Whenever cellular ATP levels are low and AMP levels are high, glycolysis is also increased. Both of these instances show that the cell is short on energy and may be directly influenced to create additional energy.
