What is the smallest biological unit of life? Cell
Define an essential amino acid. An essential amino acid cannot be produced by the human body and as such must
be take in from the environment through alternative sources (i.e) food.
Where can the two major types of nucleic acids be found in While both DNA and RNA can be found in the nucleus (center of the cell), only RNA
the cell and what are their roles? is capable of leaving the nucleus. DNA contains a vast amount of hereditary
information and is responsible for the inheritable characteristics of living organisms.
RNA is responsible for deciphering the hereditary information in DNA and using it to
synthesize proteins.

energy by converting _____ energy into _______ energy.
True or False: A defining characteristic of Protista is the True
inability of colonies to form tissue layers.

What is catabolism? The process of breaking down larger molecules into useful energy sources
Upon cellular injury, which metabolic process is involved anabolism
during the growth and repair phases of the cell.
An organism that obtains its energy (derives ATP) from phototrophic microorganism
photons of light is called a __________________

____________
Describe the energy transfer process relative to both ADP ATP has the energy (phosphate group) to donate, and ADP can accept energy in
and ATP the form of a phosphate group. Thus, ATP can be dephosphorylated (ATP-----> ADP
+ Pi), while ADP can be dephosphorylated into ATP (ADP + Pi -----> ATP)
This phosphorylation process occurs in the mitochondria of oxidative phosphorylation
