Liberty University BIOL 101 quiz 5 complete solution correct answer key
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
The energy storage molecule that connects endergonic and exergonic reactions, driving
endergonic reactions forward, is
Existing chemical bonds between atoms are broken and new ones are formed between different
atoms. This process
The activation energy of a reaction can be lowered if the reaction is catalyzed by
A single regulatory molecule can shut down multiple metabolic pathways if it is able to
In respiration, chemical energy is transferred from glucose to ATP. The energy transfer however, is
not 100% efficient. In the transfer, some of the energy is lost as
Moving ions across a membrane requires energy when
Which of the following substances would most likely enable a flagellum to drive a bacterium
forward through the medium in which it is swimming?
Metabolic pathways
Glucose gets used up in muscle cells because
Within the cell, useful chemical energy is held in stable form as
In building a protein, when amino acids are to be bonded together
Positively charged protons move freely from one side of the mitochondrial membrane
to
If moving ions across a membrane requires energy it is because
To derive energy from an ATP molecule
If the final product of a metabolic pathway begins to build up in excess, the pathway
can often be slowed down by a process called
