Answer 1

1-(c)-Carbohydrate=Protein=4 calories/gm ,Fat=9 calories/gm

2-(b)-Marathon runner:

Carbohydrate loading may be most beneficial if you are an endurance athletes-such as a marathon runner, swimmer, cyclist to maximize the storage of glycogen to the muscles and liver.

3-(c)- Carbohydrate :

Starchy Food include bread, pasta ,Rice, couscous, potatotes, breakfast cereals,oats,other grain like rye and barely.

4-(b)-Carbohydrate: because its digestion starts from oral cavity.

Fat (slowest digestion) because it is digested in intestine.

Protein digestion starts from stomach.

5-(a)- Carnosine (beta-alanyl-L-histidine) is dipeptide molecule made up of the amino acids (beta-alanine+histidine).It is highly concentrated in brain tissue and muscle cells.

6-(b)-Endocrine system involved in hormones production.

Nervous system:The network of the nerve cells and fibers which transmits nerve impulses between the body parts.

Digestive system: Break down the food, absorption and assimilation into the body.

7-(c)-Mesomorphic : Muscular and well built with a high metabolism & responsive muscles cell.

Endomorphic:Big high body fat, often pear shaped with high tendency to store body fat.

Ectomorphic:Lean,long with difficulty building muscles.

8-(c)- eicosapentaenoic acid is omega-3 fatty acid(lipid)

L-valine & amino acid (protein)

Fructose is carbohydrate sugar.
