ANATOMY

Detailed explanation-1: -Answer: (1) Their chemical structure is critical to their ability to function. Explanation: All enzymes, antibodies, and hormones have a similarity like they all have a particular and unique chemical structure which is critical to their ability to function.

Detailed explanation-2: -Answer and Explanation: A characteristic shared by all enzymes, hormones, and antibodies is that their function is determined by the shape of their molecules. This is because all of these molecules bind to specific targets and these interactions are mediated by molecular geometry.

Detailed explanation-3: -Main similarity between hormone and enzyme is :-a)Both act at particular pHb)Both are proteinc)Both are required in small amountd)Both can be used again and againCorrect answer is option ‘C’.

Detailed explanation-4: -These “chemicals” can be categorised as enzymes and hormones. One of the major differences between enzymes and hormones is that enzymes act as a catalyst for a reaction, and hormones act as messengers that trigger various functions in the body.

Detailed explanation-5: -Vitamins act as co-factors for many enzymes and also participate in regulating metabolism. Hormones are the chemical messengers that activate the target gland and regulate the metabolism by feedback inhibition.
