SUBUNIT OR BUILDING BLOCK
• Proteins are made up of Amino Acids.
• All amino acids end in “ine” (methionine,
tyrosine, etc.)
ORGANELLE OR PART OF THE
CELL
• PROTEINS are made in the RIBOSOME
from information on the RNA
PROCESS
• An example of PROTEIN is ENZYMES
• ENZYMES end in “ase” (catalase, lactase)
• ENZYMES ARE PROTEINS THAT SPEED UP
REACTIONS
• ENZYMES ARE AFFECTED BY 3 THINGS:
•
• PH, TEMPERATURE, AND CONCENTRATION
