diffusion
|
the spreading of particles in a gas or solution with a movement toward uniform distribution of particles/ the process by which molecules tent to scatter themselves thru an available space.

|
|
simple diffusion
|
unassisted diffusion of solutes thru the plasma membrane
|

glycerol and 3 fatty acids
|
|
|
cepholo-
|
head
|
|
|
proximal
|
toward the attached end of a limb or the origin of a srtucture
|
|
|
amino acids chains are building blocks of?
|
protiens
|
|
|
the body's most abundant element
|
hydrogen
|
|
|
make up of DNA
|
deoxyribonucleic acid. gentic material wi cell nucleus.1. copies self prior to cell divides. 2. infor for building proteins in the body
|
|
|
what makes up a carbohydrate?
|
(sugars, starches) carbon, hydrogen and oxygen
|
|
|
what makes up a protein?
|
carbon, oxygen and hydrogen. some nitrogen and sulfur atoms
|
|
|
where is ATP manufactured in muscles?
|
1. drives transport of amino acids across cell membrane
2. activates proteins in muscle cells for cell to shorten and work 3. provides energy to drive energy absorbing chemical reactions. |
|
|
what is the job of the ribosome?
|
site of protein synthesis. some float free in cytoplasm others attach to membranes
|
|
|
the site where ribosomes assemble prior to their migration into the cytoplasm
|
nucleolus
|
|
|
purpose of the plasma membrane
|
transparent barrier seperates cell from surounding environment.
|
|
|
job of mitochondria
|
cytoplasmic organelle w double membrane.The job of mitochondria is to perform convert glucose into energy through cellular respiration (aerobic respiration) using water and oxygen. The cell can then use the energy created or the mitochondrion can store the energy in the bonds of a chemical called adenosine triphosphate (ATP) that the mitochondrion has created
|
|
|
what is the name of an energy molecule?
|
adenosine triphosphate (ATP)
|
|
|
what is ATP
|
adenosine triphosphate
|
|
|
when is ATP used up how does the cell generate energy?
|
ADP is built back up into ATP so that it can be used again in its more energetic state. Although this conversion requires energy, the process produces a net gain in energy, meaning that more energy is available by re-using ADP+Pi back into ATP.
|
|
|
diffusion
|
the spreading of particles in a gas or solution with a movement toward uniform distribution of particles
|
|
|
2 types of passive transport
|
diffusion and filtration
|
