The sodium-potassium pump does not do which of the following actions? a) Moves sodium molecules against their concentration gradient into the cell using
ATP
b) Maintains the cell's physiological needs by establishing an electrochemical
gradient
c) Moves sodium molecules against their concentration gradient out of the cell
using ATP
d) Moves potassium molecules against their concentration gradient into the cell
using ATP

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

plant because they survive by water, sunlight, ex.

explanation:

the real answer is b. scintillation counter
