Carriers vs. channel-formers
Carrier proteins are membrane transport proteins along with the channel proteins. As membrane transport proteins, they are located in biological membranes and their primary function is to move molecules from one site to another. These transporters though differ in certain aspects.

Carrier Protein Definition
Carrier proteins are proteins that carry substances from one side of a biological membrane to the other.

electron
Any molecule or atom that accepts electrons from donor molecules and transfers them to acceptor molecules. Most are prosthetic groups (e.g., heme, copper, iron-sulfur clusters) associated with membrane-bound proteins.

. Heterozygote for a recessive allele.
Centimorgan. Metric used to describe linkage distances. 1 cM = 1% chance that a marker at one genetic locus will be separated from a marker at a second locus due to crossing over in a single generation. In humans, 1 cM=1,000,000 bp. See linkage map.

proteins
In this case, the substance actually combines with a protein and is carried from one side of the membrane to the other. (The exact details of this process remain unclear.) These proteins are specific for a particular substance.

molecule: a compound that can accept a pair of high energy molecules and transport them. eg. NADP+ s a hydrogen ion as NADPH during photosynthesis.
Chlorophyll: A pigment found in chloroplast(usually green) that absorbs light.

protein (also transport protein) A protein that transports a specific enzyme across a biological membrane during facilitated diffusion. It has a binding site that is specific for the particular enzyme it transports.

: A healthy person who is a heterozygote for a recessive trait. Also includes persons with balanced chromosomal translocations.

protein
A protein responsible for mediating the active transport of molecules from one side of the lipid bilayer to the other. Transport is carried out by a conformational change that occurs within the protein that forms an opening for specific molecules to pass through.
Channel protein ...

Active : An infected person who has visible clinical symptoms of a disease, and is capable of transmitting the disease to other individuals.
Active Site: The location on the surface of the enzyme where the substrate binds.

ATP and molecules
We most often show ATP and molecules such as NAD, FAD, and Coenzyme A as simplified grey shapes. The simplified shapes allow us to highlight the roles of these molecules while deemphasizing their large size and high level of complexity.

Most living things use the chemical DNA (deoxyribonucleic acid) as the physical of inheritance and the genetic information. Some organisms, such as retroviruses (of which HIV is a member), use RNA (ribonucleic acid) as the .

Well we send it from this to that one, this too is a hydrogen ion pump and it's pumping these hydrogen ions again across the membrane. We're starting to build up a really strong concentration gradient. Lots of hydrogen ions on one side, very few on the other.

Considering this rather complex transport system, it can be generalized that the rate of transport of any PTS-sugar depends on the concentration of the proteins and the rate of phosphate transfer between these proteins.

DNA: an abbreviation for 'deoxyribonucleic acid', the molecule of genetic information. The chain of nucleotides is held together on a polymer backbone formed by a sugar (deoxyribose) and a phosphate group (see also base).

Compounding the problems of infectious diseases are factors such as drug-resistant pathogens, insecticide resistant s, and overpopulation. Overuse of antibiotics have allowed pathogens to develop a resistance to drugs.

During the 1990s this bacterium was primarily found among individuals infected with HIV, the virus that causes AIDS. But it now appears that the bacterium can cause infections of the urogenital and respiratory tracts among individuals who are not s of HIV.
