Verified step by step guidance

Understand the role of activated carriers in cellular processes. They are molecules that store and transport energy in a form that cells can use for various biochemical reactions.

Recognize that ATP (adenosine triphosphate) and NADH/NADPH (nicotinamide adenine dinucleotide) are common examples of activated carriers. They play crucial roles in energy transfer and redox reactions.

Identify the types of energy storage in activated carriers. ATP stores energy in the form of high-energy phosphate bonds, while NADH/NADPH store energy in the form of high-energy electrons.

Clarify the nature of bonds in activated carriers. The energy stored in ATP is released through the hydrolysis of its high-energy phosphate bonds, which are covalent, not noncovalent.

Evaluate the statement about noncovalent bonds. Since activated carriers like ATP release energy through the breaking of covalent bonds, the statement that they contain strong noncovalent bonds is false.
