Question

question 11
which of the following statements is not true of proteins?
high temperature can denature proteins
plant proteins are complete proteins
a protein moleucle has amino acids connected by peptide bonds
all proteins contain c, h, n and o
question 12
which of the following statements is not true of carbohydrates?
fructose and galactose are isomers of glucose
sucrose, lactose and maltose are disaccharides
polysaccharides are highly soluble
glycogen and starch are good storage products

Explanation:

For Question 11: Plant proteins are often incomplete as they may lack one or more essential amino - acids. High temperature denatures proteins, proteins have amino acids connected by peptide bonds, and all proteins contain C, H, N, and O.
For Question 12: Polysaccharides are generally insoluble or sparingly soluble. Fructose and galactose are isomers of glucose, sucrose, lactose, and maltose are disaccharides, and glycogen and starch are good storage products.

Answer:

Question 11: Plant proteins are complete proteins
Question 12: Polysaccharides are highly soluble
