Match the enzyme with its activity change in young animals after weaning:

Match the statement with the central transporting medium for glucose:

Glucose is the main source of energy for monogastric animals and starting material for biosynthetic processes. = Blood The level of blood sugars is maintained by conversion of circulating blood glucose into glycogen and by reconversion of glycogen to glucose. = Blood Feeding considerable amounts of sucrose to young mammals results in serious diarrhoea because of sucrase insufficiency. = Blood Insulin, glucagon, and growth hormone influence glucose metabolism. = Blood Signup and view all the answers
