Apr 11, 2024 · Definition Carrier proteins are proteins in cellular membranes that mobilize different molecules by diffusion or active (ATP-driven) transport, though they are distinguishable from ion channels by ...
6 days ago · RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides and the nitrogenous bases adenine, guanine, cytosine, and uracil. Learn about the structure, types, and functions of RNA.
3 days ago · Genetic code. The story of the genetic code is the story of biology and genetics in the 19th, 20th, and 21st centuries, as well as its promises and its perils. Oswald Avery in 1944, for example, proved that the genetic code — that DNA —was indeed the carrier of hereditary information, ending more than 80 years of productive speculation.

Apr 9, 2024 · Definition Transporters are integral-membrane proteins that form a pore within the plasma membrane to allow passage of various types of molecules, including ions, small molecules and proteins.
Mar 29, 2024 · Adenosine triphosphate, or ATP, is the primary carrier of energy in cells. The water-mediated reaction known as hydrolysis releases energy from the chemical bonds in ATP to fuel cellular processes. Although cells continuously break down ATP to obtain energy, ATP also is constantly being synthesized from ADP and phosphate through the processes ...
