Cells
The organelle that controls what enters the cell
Cell Membrane
first step in cellular respiration
Glycolysis
Enzyme do this to a chemical reaction
Speed it up
a membrane that only allows in specific molecules
what causes your muscles to cramp up
lactic acid
Organelle that is jelly like
Cytoplasm
where photosynthesis takes place
Chloroplast
Enzymes do this to an activation energy
lower it
does not require ATP
passive transport
which molecules cross the cell membrane in diffusion through a membrane
iodine and glucose
Type of cells Humans are made out of
Eukaryotic
how many ATP are made in glycolysis
2 ATP
Enzymes function depending on...
Shape
This solution has a higher concentration of water molecules outside of the cell
hypotonic
which molecules did not cross the cell membrane in making connections
starch
A bunch of cells put together....
Tissue
These organisms need to use photosynthesis to make their own food
Autotrophs
molecule an enzyme reacts with
substrate
requires ATP
active transport
what is a hypothesis
an educated guess
Prokaryotic cells do not have this
a nucleus
increased _________ of enzymes, makes the reactions speed increase
concentration
definition of osmosis
movement of water across a membrane from high concentration to low concentration
why should we use a larger sample size of test subjects when testing an experiment
validity
