Which of the following statements presents an accurate picture of glucose metabolism?
◦ Because the brain needs only a certain amount of glucose, an excess presence causes insulin release from the pancreas to convert it into fat.
◦ Carnivorous animals such as cats do not need carbohydrates to obtain glucose because they synthesize their necessary glucose from the extra amino acids they consume.
◦ Because animals can convert fat back into glucose, they can be fed sugar, which will be converted into glucose when the need arises.
◦ It is advised for humans and animals to have a "low carb" diet or a grain- or starch-free diet to avoid problems with glucose metabolism.
