Describe the basic molecular structures and primary functions of the four major categories of biological macromolecules:
a. carbohydrates
b. lipids
c. proteins (amino acids)
d. nucleic acids

Carbohydrates

Explanation:

Carbohydrates get broken down into glucose by the acid in your stomach and small intestine, and the glucose gives energy to your cells especially brain cells and neurons. Lipids like triglycerides store energy for cells. Proteins build up many parts of your body. Carbohydrates like monosaccharides have a formula of C6,H12,O6 and are kind of hexagon shaped. Different lipids have different structures, triglycerides is like three lines because they are made of 3 fatty acids and glycerol. Different proteins have different structures, alanine is lined with oxygen atoms and hydrogen. DNA is two lined with proteins on it and RNA is one lined with proteins.

a plastic spoon that has a temperature of 78° f is placed into a bowl of soup that has a temperature of 84° f. which of these correctly describes what will happen?

energy as heat moves from the soup to the spoon.
