BIO 168 CH.2 (PT.2) Flashcards
Dehydration Synthesis is where
2 monomers have a boy and girl baby (OH), they get rid of H2O, and they are only left with O baby to share
Hydrolysis is where
2 monomers have only an O baby, they get preggers and add H20 and they now have a boy and a girl baby (OH) of their own
Identify the term that describes the attraction between water molecules only.
cohesion
the capacity to do work is known as
energy
Glucose is stored in the liver and muscles in the form of a polymer called
glycogen
A method of writing a summary of the changes that occur in a chemical reaction is a
chemical equation
What is the capacity to do work called?
energy
chemical energy is a…
form of potential energy, synthesis of molecules, and used to establish concentration gradients
All of the decomposition reactions in an organism are collectively referred to as
catabolism
Anabolic reactions are ______ reactions.
synthesis
Which type of reaction involves both synthesis and decomposition?
exchange
What type of reaction results when small molecules combine to make a larger one?
synthesis
The measure of how quickly a chemical reaction takes place is known as the
reaction rate/time
If the rate of a reaction leads to a net gain in product then the reaction is considered
irreversible
A biologically active catalyst is known as a(n)
enzyme
If, over time, products and reactants are formed at the same rate, then the reaction is said to be
reversible
The smallest enzymes are around ______ amino acids long
60
True or false: Activation energy is only required in endergonic reactions.
False
An enzyme that is catalyzing a reaction at the maximum rate is said to be ______.
saturated
The activation energy of a catalyzed reaction is ______ that of an uncatalyzed reaction.
lower than
A multistep process in which organic molecules like glucose, fatty acids, and amino acids are broken down to extract energy for ATP production is called
cellular respiration
