Summarize active transport In your answer consider the direction of transport and any external energy or special structures that are needed in the process .

an area of lower concentration to an area of higher concentration.

ATP

Primary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.

the uptake of glucose in the intestines in humans and the uptake of mineral ions into root hair cells of plant

membrane pumps (such as the sodium-potassium pump) and vesicle transport.

Primary Active Transport.

The Cycle of the Sodium-Potassium Pump.

Generation of a Membrane Potential from the Sodium-Potassium Pump.

Secondary Active Transport.

Active Transport.

Explanation:

oxidation

explanation:

answer

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
