More than two versions
For most chemical reactions in the non-living world, the energy required to break bonds in
the reactant molecules
In biosynthesis of a protein, energy for bonding amino acids together comes from
A producer organism is called a “producer” because it produces
Physicists define energy as
Reactants like hydrogen and oxygen molecules and are converted into a product like water
molecules in the course of
Systems that convert energy from one form to another are
In a long metabolic pathway, the multiple changes made to an initial reactant molecule are
entirely controlled by
Energy-releasing reactions drive biosynthetic ones forward by contributing to a pool of
If bacteria can get their energy for life from a single kind of chemical reaction, then that
reaction
An endergonic reaction always
An allosteric enzyme
A useful way for a cell biologist to define energy is
In nature, as energy freely changes from one form to another
On a cold day, your cells depend on ________ to maintain an operating temperature of 37
degrees Celsius.
Whenever chemical bonds are broken, energy is __________. Whenever chemical bonds
form, energy is __________.
Producer organisms convert _______ energy to chemical energy—the energy of C―H and
C―O―H bonds.
Three phosphate groups linked to a ribose sugar which, in turn, is linked to a pyrimidine base
known as adenine: this phrase describes the structure of
An excess amount of product accumulates at the end of a metabolic pathway. The product
then binds to the allosteric site of the first enzyme along the pathway shutting down the
pathway. We call this process
