(a)
Interpretation:
The hormone released by the body when someone is diagnosed with diabetes and the class of hormone in which it belongs has to be given.
Concept Introduction:
Hormones: Hormones are chemical messengers which are secreted by the cell in endocrine system and are transported along the blood to stimulate the target cells having the corresponding receptors.
Hormones are of three types,
- 1. Amino acid derivatives: It is a derivative of an amino acid formed by the reaction at the side chain
functional group ,carboxylic acid group, amino group or by the replacement of a hydrogen atom by heteroatom. - 2. Polypeptides: Polypeptides are organic
polymers having several amino acids attached to each other in a chain. - 3. Steroid: Steroids are a type of organic compound having a molecular structure with four rings connected to each other.
Insulin is an example for a polypeptide hormone consisting of 51 amino acids. The insulin is generated by pancreas and is functioned at the cell so that the cells take glucose for the generation or storage of energy.
(b)
Interpretation:
The part of body where insulin is generated has to be given.

Interpretation:
The mode in which the hormone is transported to cells that need it to allow glucose to enter has to be given.

(d)
Interpretation:
The hormone is whether expected to enter the cell to carry out its function has to be explained.

- Imagine that aldolase can react with the seven carbon molecule Sedoheptulose-1,7-bisphosphate (below). Use the mechanism to predict the two products generated. Please draw out the stereochemistry in a fischer projection.arrow_forwardSodium borohydride (NaBH4) is a potent inhibitor of aldolase. It is known to ONLY inhibit theenzyme when it is complexed with substrate. Treatment of the enzyme alone has no effect.What is the mechanism for this inhibition? Please draw out the mechanism and show how it inhibits this.arrow_forwardShow the fate of the proton on the 4-Oxygen molecule of F-1,6-BP.
