biology 7.3 ATP provides energy for cellular work
main energy source that cells use for most of their work
ATP - adenosine triphosphate
In what way is ATP like a compressed spring?
ATP is like a compressed spring because the phosphate groups are negatively charged so the crowding of the negative charges contributes to potential energy stored in the ATP. Storing this energy is like compressing a spring. When the spring relaxes, the potential energy is released.
Each phosphate group is ___________ charged and repel each other
negatively
What is the source of energy for regenerating ATP from ADP?
organic molecules from food.
ATP tail is like a spring that releases its _______________ ______________ when relaxed
potential energy
An ATP molecule contains potential energy, much like a compressed spring. When a phosphate group is pulled away during a chemical reaction, energy is ________________.
released
a "tail" with three phosphate groups
triphosphate
the source of energy used for most work
triphosphate
nitrogen-containing compound adenine + five carbon sugar called ribose
adenosine
List three main types of cellular work
chemical work, mechanical work, and transport work
