a ) Based on Diagram, explain the assimilation of the following types of food
( i ) glucose
( ii ) amino acids
( iii ) lipids [ 10 marks ]
Suggested Answer:
Able to explain the assimilation of digested food of glucose , amino acids and lipids
Sample answer
Glucose
P1 : Excess of glucose in the blood is converted to glycogen and stored in the liver
P2 : In the liver , if glucose level in blood is low glycogen is converted to glucose
P3 : Excess of glycogen is converted to lipids by the liver
P4 : Reaching the body cells , glucose is oxidized to release energy in cellular respiration
Amino acids
P5 : In liver , synthesized of plasma protein from amino acids
P6 : In liver excess of amino acids ( cannot be stored in the body but) undergo deamination process.
P7 : Urea is then eliminated by the kidney
P8 : In body cells , amino acids is used to synthesise new protoplasm and repair of damaged tissues
P9 : In body cell , amino acids is used to synthesise
enzymes/antibodies/hormones
Lipids
P10 : Excess lipids is stored in adipose tissues
P11 : Phospholipids and cholesterol make up the plasma membrane Any 10 points
