Question about a Crayfish Digestion...?

Question

trace the pathway of a crayfish's meal and its digested nutrients from the mouth to the abdominal flexor muscl what molecule must be picked up along this pathway in order for the muscle cell to obtain energy from the food particles and wehre is this molecule absorbed into the blood?

Answer 1

"The digestive tract (figure 1a) consists of the foregut, which includes an enlarged stomach, part of which is specialized for grinding; the midgut, which extends from the foregut; and the hindgut, which leads to the anus and functions in water and salt regulation (Miller and Harley, 1992; Snodgrass,1965). The digestive gland secretes digestive enzymes and aids in the absorption of the products of digestion (Pennak, 1989). "
An example of a molecule that would be found is glucose. It would be absorbed directly from food in the digestive system into the body (the interstitial fluid) and then into the blood. It is fairly soluble in water. Many cells have special transporters, like the Na+/glucose co-transporter to increase the uptake of glucose by cells. Glucose in skeletal muscle is stored in the form of glycogen.
