Chapter 5 Quiz Biology Worksheet

The ability to do work
Stored energy that can be used for motion
Energy of motion
Energy conversion to heat, Heat energy
The study of energy or heat
Can never be created nor destroyed, amount of energy, in the universe remains constant
Amount of energy transforming from potential to heat energy, or entropy in universe is increasing
The starting molecules of a chemical reactions
Molecules at the end of a chemical reaction
Reactions have products w/ more energy than the reactants (uses & stores energy) spontaneous
An initial input of energy by destabilizing existing chemical bonds
reactions become more spontaneous if their activation is lowered
Catalysts used by cells to perform particular reactions
Enzymes lower activation energy by binding specific molecules and stressing the bonds to make the reaction more likely to proceed
includes all the chemical and physical process continuously occurring in living cells
Is the process by which food is changed into living tissue
Is the process by which food is converted into energy and wastes of a simpler chemical composition
Series of reactions of the product of one reaction is the substrate of the next
What do free "inorganic" phosphates do?
When an atom or molecule loses an electron
When an atom or molecule gain an electron
Have "the power" causes something else to be reduced
Where is energy "Stored" in ATP molecule?
electrons pass from atoms or molecules to one another as part of many energy reactions
Provide energy for the initiation of endergonic reactions.
