Question

question 9
why is the sequence of amino acids important to the properties of a protein?
o it provides structural support, the structure determines the function
o it stores energy and provides covering to avoid water loss
o it stores energy and provides structural support for cells
o it retains and transmits important biological information
the 1:2:1 ratio of carbon to hydrogen to oxygen is seen in which group of organic compounds?
o nucleic acids
o proteins
o lipids
o carbohydrates

Explanation:

Proteins are made up of amino - acids. The sequence of amino - acids determines the protein's structure and function. Different sequences lead to different shapes and properties of proteins. Carbohydrates typically have a 1:2:1 ratio of carbon to hydrogen to oxygen.

Answer:

Question 9: C. It provides structural support, the structure determines the function
The 1:2:1 ratio question: A. carbohydrates
