How do proteins that are pumps differ from those that are channels?

They differ mainly by their shapes but they are an integral part of the membrane itself. The ones that are channels are open in the center. They use no energy.The ones that are pumps do not have a free opening. Also these pumps use energy to allow them to work. This use of energy (ATP) causes them to move objects against the concentration gradient.

∙ 11y agoThey are both proteins that span the cell membrane - but the difference is in how they move substances/molecules/ions across.
Channels, once open, allow things to move through them (down the concentration gradient from an area of high to an area of low concentration).
Pumps come in many different varieties, but essentially they grab the substance and then change shape to allow it entry into the cell (instead of just opening and creating a gap). Some of these move things against their concentration gradient (from areas of low to high concentration).

What is the fundamental difference between carrier proteins that participate in facilitate diffusion and carrier proteins that function as pumps?
facilitated diffusion does not require energy, as it travels from a higher concentration gradient to a lower one(passive transport). Pumps do require energy to function(Active transport). This energy needed is ATP.
What is the function of the peripheral protein?
Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. These molecules attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer. The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. In contrast to integral membrane proteins, peripheral membrane proteins tend to collect in the water-soluble component, or fraction, of all the proteins extracted during a protein purification procedure. Proteins with GPI anchors are an exception to this rule and can have purification properties similar to those of integral membrane proteins.
What is protein pump?
it is a protein in a quatenary structure or three d sturucture with in the cell wall and transports macro molecules, hydrophobic molecules or molecules that are going agains the concentration(respectively are to big to go through, repel the cell wall, or are going against the traffic of osmosis) by using those molecules as a substrate( something that fits into a protein) and moves to the other side of the wall
What do ribosome do in animal and plant cells?
Ribosomes function in the production of proteins. These proteins include those that will remain in the cell and those that will be transported out of the cell.

How do transport proteins that are pumps differ from that are channels?
Transport proteins that are pumps differ from those that are channels in that when it pumps, it moves materials against concentration gradient. Other wise, from low to high concentration levels. Channels move materials down a concentration gradient, requiring no energy expenditure by the cell. From high concentration to low concentration levels.

How do proteins of food differ from those of the organism who consumed them?
Proteins in food are genetically programmed to give energy to the organism which eats them once digested, broken into its simplest form( amino acids ) and assimilated into the organism's system.The proteins however, in an organism are meant to either to provide structural strength and integrity to muscles or to digest food.

How did the Renaissance scholar's differ from those of medieval scholar's?
Renaissance scholars focused on humanism, individualism, and a revival of classical learning and culture, while medieval scholars were more centered on theology, scholasticism, and religious teachings. Renaissance scholars were more interested in the arts, literature, and science, while medieval scholars focused on deciphering and interpreting religious texts and doctrines.
What does N1H1 stand for?
Hemagglutanin & Neurominadase are surface antigens. The number '1' refers to the specific sub-type of those antigens. The sub-types differ in their basic structure.

it is on the channels boomerang and cartoon network, may be on some other channels if so, i do not know those channels
