Biology reactions
The compound is broken into its constituent parts
decomposition
bonds broken and elements released
decomposition
Which type of reaction is dependent on the concentration of the products and reactants?
reversible
simultaneous decomposition and synthesis
reversible
The reactants used to form the products can also be synthesized from those products
reversible reaction
A _____ reaction occurs when a molecule is formed from the bonding of atoms, ions or simpler molecules.
synthesis
molecules formed from components
synthesis
Two or more units are added together to form a new compound
synthesis reaction
A plant must supply energy through photosynthesis in order for its complex starch molecules to breakdown to a simple sugar. True or False
False
Chemical reactions will occur independently of the reactant's temperature. True or False
False
The concentration of reactant product influences the rate and net direction of a reversible reaction
Law of Mass Action
What occurs during a decomposition reaction?
A compound partitions into its components.
The rate and direction of reactions are greatly influenced by the:
Law of Mass action or molecular concentration because they relate to the same principle
The process by which organisms decompose food and synthesize energy and tissue is _____.
Metabolism
When fats decompose in an organism, energy is released. True or False
True
The energy required to start a chemical reaction
activation energy
A substance which will resist changes in pH within reasonable limits
buffer
Accelerates a chemical reaction without being used up in the reaction
catalyst
When a reversible reaction is occurring in both directions at the same rate
chemical equilibrium
A _____ reaction occurs when ionic or covalent bonds are broken and elements, ions, or simpler molecules are formed.
decomposition
What is required for reactants to form bonds?
energy input
A protein molecule which speeds up a specific chemical reaction in biological systems
enzyme
An _____ reaction occurs when the bonds of the reacting compounds are broken and new combinations are formed.
exchange
molecules rearrange and form new molecules
exchange
A chemical reaction where the substrates trade constituent parts
exchange reaction
Chemical equilibrium results if:
forward reaction rate equals reverse reaction rate

friction
All of the chemical reactions in the organism for maintenance of the processes of life
metabolism
A substance which results from a one-way chemical reaction is called a
product
That which is produced as a result of a chemical reaction
product
A substance which enters into a chemical reaction is called a
reactant
A _____ reaction occurs when the reactants are reproduced by reaction of the products.
reversible
The products and reactants of a(n) _____ reaction will form at the same rate when equilibrium is attained.
reversible
