Carbohydrates are found in virtually all foods except:
- sucrose, maltose and lactose
- glucose, galactose and fructose
- starch, glycogen and dietary fibre
- amylose, pectin and dextrose
a. sucrose, maltose and lactose
The making of a disaccharide from two monosaccharides is an example of:
The storage form of glucose in the body is:
The significant difference between starch and cellulose is that:
- starch is a polysaccharide, but cellulose is not
- animals can store glucose as starch, but not as cellulose
- hormones can make glucose from cellulose, but not from starch
- digestive enzymes can break the bonds in starch, but not in cellulose.
d. digestive enzymes can break the bonds in starch, but not in cellulose.
The ultimate goal of carbohydrate digestion and absorption is to yield:
- dietary fibre
The enzyme that breaks a disaccharide into glucose and galactose is:
With insufficient glucose in metabolism, fat fragments combine to form:
- phytic acids
- ketone bodies
d. ketone bodies
