pressures
what is hypertonic
when the cell has a higher solute concentration than solvent compared to body fluids
what is DNA
Deoxyribonucleic Acid. Double Helix of genetic information.
what does ATP stand for
Adenosine Triphosphate
what is active transport
A substance using energy to enter or leave the cell.
What is the nucleus
Control center of the cell
what is hypotonic
When a solution has a higher concentration of solvents to solutes
what is RNA
Ribonucleic Acid. Single helix of genetic information
What makes ATP
Mitochondira
what is endocytosis
A substance leaving the cell using energy.
Where is the nucleus found
Typically center of the cell
what is isotonic
when a cell has an equal balence of solvents and solutes
what is mRNA
Messenger ribonucleic acid. Sends messages around the cell.
What does ATP power
Powers muscle contraction,nerve impulse transmission, and aids in protein synthesis
what is pinocytosis
A substance entering the cell through leftover droplets and liquid molecules.
What does it store
Genetic information
what is osmotic pressure
pressure used to prevent the solvent from flowing in even more. Higher in hypotonic solutions.
what is tRNA
Transfer ribonucleic acid. Translates genetic information
What does ATP do to give energy
Donates a phosphate group to another molecule
what is phagocytosis
when a substance enters the cell through the membrane engulfing it.
What is held inside of the nucleus
the nucleolus
what is Diffusion
movement of molecules from high to low concentration
What is rRNA
makes polypeptides that makes proteins
what is ATP after it is used in a chemical reaction
ADP; Adenosine Diphosphate.
what is exocytosis
what is chromatin
DNA that tightens up into chromosomes during mitosis. It's around the nucleolus
