10. When the tertiary structure of proteins is disrupted, the proteins lose their functionality. This is called ____________ of proteins. • A) hydrolysis • B) denaturation • C) digestion • D) hydrogenation

Homework Answers

Answer #1

Answer 1- a) myoglobin

Reason- The type of proteins present in the meat are:- myosin, actin, collagen and elastin. These are responsible for the overall structure of muscle.

Answer 2- b) keep the oil and water mixed

Reason- protein acts as a emulsifier. It breaks the bigger fat molecules into the smaalsr ones.

Answer 3- b) false

Reason- The air cell is a air pocket forms between the outer and inner membranes at the larger end of the egg.So, as the egg gets older, the size of air pocket gradually increases.

Answer 4- a) true

Reason- the fats consists of three fatty acids and a glycerol, thus named as triacylglycerols or triglycerides. It is formed by the joining of three fatty acids to a glycerol backbone in a dehydration reaction.
