Concept introduction:

Biological molecules like proteins, carbohydrates, lipids, and nucleic acids interact to carry out activity necessary to living cells.

Answer to Problem 91A

Proteins perform various functions in living cells like structural support and muscle contractions, carbohydrates provide energy, lipids make cell membranes, store energy in energy and nucleic acids store and transmit the genetic information.

Explanation of Solution

Proteins perform various functions in living cells like regulation of chemical reactions, transport of materials, structural support and muscle contractions.

Carbohydrates provide energy and most structural material for the living things.

Lipids make cell membranes, store energy in the living body and regulate cellular processes.

Nucleic acids store and transmit the genetic information.

Conclusion

Proteins, carbohydrates, lipids and nucleic acids perform various activities in living cells.
