What does "denature" an enzyme mean?
enzyme attached to the substrate.
enzyme decomposed and disappeared.
enzyme unfolded/changed shape and no longer functions.
enzyme sped up the process of breaking down a substrate.

What do centrioles do?
break down with digestive enzymes
used in cell division
provide energy/ATP
surround and protect the cell
Enzymes ALWAYS
LOWER activation energy
INCREASE activation energy
STABLIZE activation energy
What do enzymes do to chemical reactions?
they slow them down
they speed them up/accelerate them
they stop them from happening
they don't do anything
Define a Virus:
Outside of a host cell, viruses are little more than bits of DNA or RNA surrounded by a protein coat.
Viruses can remain dormant for long periods of time until they come in contact with a host cell.
The infected cell begins replicating the virus and/or making viral proteins
A virus is a typical type of cell with a nucleus
Select the correct choice concerning a protein:
Proteins are made of repeating units called amino acids. The sequence of the amino acids determines the job of the particular protein.
Proteins are made of repeating units called nucleotides. The sequence of the nucleotides determines the job of a particular protein.
Proteins form a bilayer to build selectively permeable cell membranes.
Proteins are similar to sugars and provide quick energy for cellular functions.
Osmosis is always:
a type of passive transport that moves water
a type of passive transport that moves sugar
a type of active transport that moves water
a type of active transport that moves oxygen
Enzymes are a type of protein that:
use amino acids to build polypeptides
work as quick sugars
catalyze chemical reactions
primarily make up the cell membrane
holds the DNA which contains the instructions necessary for protein production
nucleus
mitochondria
cholorplast
ribosome
What is the function of the mitochondria?
Structure that manufactures ribosomes
