Ineed ! select the atoms present in each of the following macromolecules

which of the following molecules is the smallest
a glucose
b starch
c disaccharide
d nuclei can acid

plants store glucose as this molecule
a myosin
b glycogen
c baleen
d starch

all amino acids have a similar structure. which component is responsible for the difference in the 20 amino acids?
a the carboxylic acid
b the r group
c the central atom
d the amino group

the salvia in your mouth contains amylase. amylase is an enzyme that breaks down starch and glycogen into glucose, simple sugars. the sequence of amino acids in the amylase is an example of witch level of protein structure?
a primary
b secondary
c tertiary
d quarternary

1: option C, 2: option D, 3: option B, 4: option C.

Explanation:

1. Option C. Disaccharide.

Disaccharide is formed as a result of two monosaccharides joined by glycosidic linkage to form a disaccharide.

2. Option D. Starch.

Plants stored their manufactured glucose in form of starch. The glucose is manufactured during photosynthesis.

3. Option B. The R group.

The R group differs among amino acids, they are radicals and it determines the differences between these amino acids (this simply implies that the R group is the variable part of amino acids). The R groups are very essential because it is their properties that determines the structure and function of protein.

4. Option C.

Most tertiary structures can be either globular or fibrous. Generally, proteins such as enzymes which are basically non-structural proteins are globular, they look spherical.

The enzyme amylase is globular in shape therefore it is a tertiary structure protein.

the answer is:

carbon dioxide

not too sure but maybe in the hot springs.
