2.1.5 Carbohydrate Metabolism and Glucose Regulation

What is the aim of the digestion?

• Obtain matter and energy

• Obtain nutrients from food and break it down into small molecules, which are then absorbed

• Break down food into inorganic nutrients

• Obtain nutrients form food and transport it to the cells

Foods that are high in carbohydrates are broken down by your digestive system into...

• glucose

• proteins

• nucleic acids

• fats

Sugars are absorbed and are initially transported to the ...

• blood stream

• muscles

• fat cells

• liver

What will immediately happen after you eat a meal?

• blood glucose decreases

• blood glucose increases

• insulin decreases

• the cells will break down the glucose

• insulin

• glucagon

• both insulin and glucagon

• neither insulin nor glucagon

Which hormone is produced by the pancreas?

• insulin

• glucagon

• both insulin and glucagon

• neither insulin nor glucagon

Which hormone is produced when the blood glucose concentration is below normal?

• insulin

• glucagon
