Glucose
D
Nucleic acids
Verified step by step guidance1
Identify the primary forms of energy storage and usage in cells. Cells primarily use carbohydrates, lipids, and proteins for energy, but the immediate source of energy is typically a carbohydrate.
Understand the role of glucose in cellular metabolism. Glucose is a simple sugar and a key energy source for cells. It is metabolized through glycolysis, the citric acid cycle, and oxidative phosphorylation to produce ATP, the energy currency of the cell.
Compare glucose with other biomolecules listed: amino acids, lipids, and nucleic acids. Amino acids are primarily building blocks for proteins, lipids are used for long-term energy storage and membrane structure, and nucleic acids are involved in genetic information storage and transfer.
Recognize that glucose is the primary molecule used in cellular respiration to generate ATP quickly and efficiently, making it the cell's primary form of immediate energy.
Conclude that among the options provided, glucose is the correct answer as it is the primary form of energy used by cells for immediate energy needs.
