Cell Membrane
maintains homeostasis by controlling what enters and leaves the cell
suspends the organelles and provides an environment for chemical reactions within the cell
makes proteins
provides structure for cells and movement of organelles
Cytoplasm
maintains homeostasis by controlling what enters and leaves the cell
suspends the organelles and provides an environment for chemical reactions within the cell
makes proteins
provides structure for cells and movement of organelles

makes proteins
provides structure for cells and movement of organelles
Nucleus
stores genetic information (DNA)
makes and transports proteins
makes lipids and membranes (also detoxifies and stores calcium)
modifies, sorts, and ships proteins
Rough Endoplasmic Reticulum
stores genetic information (DNA)
makes and transports proteins
makes lipids and membranes (also detoxifies and stores calcium)
modifies, sorts, and ships proteins
Smooth Endoplasmic Reticulum
stores genetic information (DNA)
makes and transports proteins
makes lipids and membranes (also detoxifies and stores calcium)
modifies, sorts, and ships proteins
Golgi Bodies
stores genetic information (DNA)
makes and transports proteins
makes lipids and membranes (also detoxifies and stores calcium)
modifies, sorts, and ships proteins
Mitochondria
creates energy (ATP) from food; site of cellular respiration
stores food, water, or wastes with the cell; plant cells have a special vacuole
uses enzymes to digest bacteria, viruses, and old organelles (old cell parts are recycled)
create special structures called spindle fibers that are used in cell division
Lysosome
creates energy (ATP) from food; site of cellular respiration
stores food, water, or wastes with the cell; plant cells have a special vacuole
uses enzymes to digest bacteria, viruses, and old organelles (old cell parts are recycled)
create special structures called spindle fibers that are used in cell division
Chloroplast
provides shape, structure, and protection for the cell
site of photosynthesis; uses the sun's energy to produce food
stores water in order to maintain plant shape (if a plant needs water, it wilts)
site of cellular respiration
Central Vacuole
provides shape, structure, and protection for the cell
site of photosynthesis; uses the sun's energy to produce food
stores water in order to maintain plant shape (if a plant needs water, it wilts)
site of cellular respiration
Enzymes are an example of
Lipids
Carbohydrate
Protein
Nucleic Acid
BUT above a certain temperature, the structure of the enzyme changes.
The enzyme then loses its shape/unfolds as does the active site. This means the enzyme activity is reduced and the enzyme is said to be (a) .
Homeostasis means that the _____ stays stable while the outside changes
inside
outside
hot
cold
A process that does NOT use cellular energy is know as
active transport
passive transport
metabolic transport
living transport
Select all correct answers: An example of passive transport is

low, high
high, low
low, low
high, high

In what type of environment would you find isotonic cells?
pure water
equilibrium
salty water
all of the above
Fermentation, an example of anaerobic respiration, is a:
life process that occurs when no oxygen is available
life process that occurs when carbon dioxide and nitrogen is available
life process that occurs when hydrogen is available
life process that occurs when oxygen is available
Adam’s body is not getting enough oxygen. What form of respiration is his body using to release some energy from food?
Anaerobic Respiration
aerobic Respiration
What has to be absent for fermentation to occur?
carbon dioxide
oxygen
The first step in getting energy in the cell by breaking down glucose is known as
the Krebs cycle
electron transport
fermentation
glycolysis
What are the products of photosynthesis?
glucose and oxygen
carbon dioxide and water
