Which of the following is a primary function of carbohydrates in living organisms?
A
Catalyzing biochemical reactions
B
Energy storage and supply
C
Forming the main component of cell membranes
D
Encoding genetic information
Verified step by step guidance1
Understand the role of carbohydrates in living organisms. Carbohydrates are organic molecules composed of carbon, hydrogen, and oxygen, typically in a 1:2:1 ratio. Their primary function is related to energy storage and supply.
Eliminate the incorrect options by analyzing their functions: Catalyzing biochemical reactions is a function of enzymes, which are proteins, not carbohydrates.
Next, consider the option 'Forming the main component of cell membranes.' This is primarily the role of lipids, specifically phospholipids, not carbohydrates.
Now, evaluate the option 'Encoding genetic information.' This is the function of nucleic acids, such as DNA and RNA, not carbohydrates.
Conclude that the correct answer is 'Energy storage and supply,' as carbohydrates like glucose and glycogen are key molecules used by organisms to store and provide energy.
