Why do plants use cotransporters instead of ion channels to transfer anions into cells?

because contransporters can transfer anions against the membrane potential gradient where as ion channels can only transfer from high consentrations to low consentrations

What ion is found on the inside of a neuron?
The main ions found inside a neuron are potassium and organic anions. The organic anions cannot cross the cell membrane but potassium ions can. It is the diffusion of potassium ions out of the cell which is the main cause of the resting membrane potential.
In hydrolysis is water added or removed?
Hydrolysis is a chemical reaction. Molecules of water are split into hydrogen cations and hydroxide anions in the process of a chemical mechanism.
Inside the cell a lot of negative charges are present on what in the cytoplasm?
Proteins- the carboxyl group in the backbone of all proteins is negatively charged. and also some amino acid residues are negatively charged. there is also alot of phosphate groups in various forms that are also negatively charged, as well as anions such as chlorine which are stored in the cell to generate a membrane potential.
What is an atom that has given up or taken on electrons?
I believe you mean an ion, which is an atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons. atoms that lose electrons are metals that become positively charged cations. atoms that gain electrons are non-metals that become negatively charged anions.
Most common extracellular ion is what?
There are more than 2. Any molecule with a negative charge is an anion. Inside cells, these include bicarbonate, chloride, ATP, and any other molecule with phosphate groups, and amino acids having negative charge (glutamate, aspartate). So, there are a wide variety of intracellular anions.
Why are anions larger?
Anions have supplementary electrons.
Introduction determination of anions in aqueous solution?
introduction of anions
How many anions are there in 3.50 g of MgBr2?
There are 22,9.10e21 anions.
What type of anions are formed in the halogens?
anions with -1 charge
Are oxide ions cations or anions?
anions oxides are O2-
A anions and xenons b anions and cations c cations and xenons d xenons and anions Which of these are ions?
The ions are b, anions and cations. Note that xenon is not an ion, it is a noble gas.
How anions reacts with silver nitrate?
how anions react with silver nitrate
What characteristics is shared by most simple polyatomic ions?
They are Anions.
What is the cation on MnI2?
Mn2+. Cations are positively charged anions are negative. Metals such as Mn manganese form positively charged ions, cations , when they transfer electrons to non metals such as iodine I.
In a crystal of an ionic compound each cation is surrounded by the number of?
Usually anions, as in sodium chloride. However in some hydrates the cation may be surrounded by a coordination sphere of water molecules
Do anions and cations share electrons during ionic bonding?
Yes anions and cations share electrons. Anions gain electrons and cations loose electrons.
Are anions and cations ion?
Yes. Anions are negative ions and cations are positive ions.
