Channel proteins are proteins that enable the transportation of certain substances and materials across cell membranes. Channel proteins consist of a wide group of more than 20 different organic compounds and, although they share the umbrella title of channel proteins, these substances play different roles. Channel proteins are formed in long chains of amino acids; the sequence of these chains dictates the function and shape of each channel protein.Continue Reading
Bobcats, or Lynx rufus, are endemic to the North American continent. Highly adaptable, these animals thrive in forests, swamps, deserts, agricultural areas and sometimes even in suburban areas. It is estimated that there are 725,000 to 1,020,000 bobcats in the wild. Its name is based on the appearance of its tail, which looks cut or "bobbed."
Bobcats are rarely seen because they are mostly active at night. As strict carnivores, these fierce hunters prey on rabbits, birds, mice, squirrels and other smaller animals. Once they have spotted their prey, they calculate its exact location, and then leap as long as 10 feet to pounce on top of it to pin it down.Learn more about Molecular Biology & DNA
Catabolic pathways involve chemical reactions that convert complex organic molecules into simple substances, and they either store energy or release it as heat. Anabolic pathways involve chemical reactions that build novel molecules and make use of energy stored in the catabolic reactions.Full Answer >
The substances making up the sides of the DNA ladder are alternating phosphate groups and deoxyribose sugar molecules. Phosphate groups are inorganic molecules made up of one atom of phosphorus chemically bonded to several oxygen atoms. Deoxyribose is a type of sugar featuring five carbon atoms.Full Answer >
The plasma membrane, also known as the cell membrane, protects the inside of the cell and is able to select which substances are allowed into the cell. Plasma membranes are mainly made from phospholipids and cholesterol, although cholesterol is not found in plant cell membranes.Full Answer >
Ribosomes are a type of organelle found in every cell, and their main function is to synthesize proteins for use throughout the cell. In the ribosomes, individual amino acids are arranged into long protein chains according to the sequence of mRNA, or messenger RNA. It is the ribosome's job to read the sequence of mRNA and translate it into the correct sequence of amino acids for each protein that must be made.Full Answer >
