Multiple Choice
Both lipids and carbohydrates are important in animal cells because both:
A
contain nitrogen as a major element
B
store energy for cellular processes
C
are primary components of nucleic acids
D
function as enzymes in metabolic reactions
Verified step by step guidance
1
Understand the role of lipids and carbohydrates in animal cells. Lipids are primarily used for long-term energy storage and insulation, while carbohydrates are used for short-term energy storage and as a quick energy source.
Analyze the options provided in the problem. For example, lipids and carbohydrates do not contain nitrogen as a major element; nitrogen is primarily found in proteins and nucleic acids.
Evaluate the statement about nucleic acids. Lipids and carbohydrates are not primary components of nucleic acids; nucleic acids are composed of nucleotides, which include a sugar, phosphate group, and nitrogenous base.
Consider the role of enzymes in metabolic reactions. Lipids and carbohydrates do not function as enzymes; enzymes are typically proteins that catalyze biochemical reactions.
Conclude that the correct answer is related to energy storage. Both lipids and carbohydrates store energy for cellular processes, making this the most accurate description of their shared function in animal cells.
