Metabolism
What process consists of chemical reactions that breakdown or spend molecules for energy?
Metabolism
What does the acronym "ATP" stand for?
Adenosine Triphosphate
What does the acronym "ADP" stand for?
Adenosine Diphosphate
How often does the ATP cycle operate within living cells?
It is constant in cells
Which molecule is used by the cell specifically for energy storage?
Glucose
What happens to molecules during metabolic reactions to release energy?
They are broken down or spent
How many phosphate groups are contained in one ATP molecule?
3 phosphate groups
What event causes ATP to convert into ADP?
One of the phosphate groups breaks off
What provides the required energy to form ATP from ADP?
Food
Is ATP better suited for energy transfer or energy storage?
Energy transfer[2]
What is the term for all chemical reactions in a cell that handle energy molecules?
Metabolism
What is the nitrogenous base found in an ATP molecule?
Adenine
What general process moves a phosphate group between molecules to transfer energy?
Phosphorylation
What compound is recycled back into ATP when energy from food is supplied?
ADP (Adenosine Diphosphate
In the monetary analogy, which molecule represents dollars for immediate transactions?
ATP
Why must cells continually undergo metabolic reactions?
To break down or spend molecules to get energy
What type of sugar molecule forms the core structure of ATP?
Ribose
What specific group moves between molecules during phosphorylation?
A phosphate group
What continuous cellular cycle connects ADP back into ATP using food energy?
The ATP Cycle
In the monetary analogy, which molecule represents stored wealth like gold?
Glucose
What two actions on molecules define metabolism in the notes?
Breakdown or spending of molecules for energy
What are the three structural components of an ATP molecule?
Adenine (nitrogenous base), ribose (sugar), and 3 phosphate groups
Describe how phosphorylation transfers energy in the cell.
A phosphate group moves between molecules[2]
How does energy from food contribute to maintaining cellular work via the ATP cycle?
Food provides the energy needed to re-attach a phosphate group to ADP to recreate ATP
Explain the gold and dollar analogy regarding cellular energy.
Glucose acts like gold (dense, stored energy), while ATP acts like dollars (easily spent/transferred energy)
