Skeletal muscle contractions do in fact demand large quantities of ATP (adenosine triphosphate), the universal source of cellular energy. In order to accommodate this necessity, skeletal muscle cells (myocytes) are packed with mitochondria, which are the energy powerhouses of the cell.
However, the production of ATP would halt in mitochondria if the necessary substrates (fuels) are not present to enter these organelles, mainly glucose and oxygen (O2). So, additionally, skeletal muscle is also loaded with glycogen, a storage form for glucose (as starch), and myoglobin, an enzyme similar to hemoglobin in that it binds an O2 to hold it for use during contraction.
Explanation:
nonliving characteristics include the fact that they are not cells have no cytoplasm or cellular organelles and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery. And viruses can infect animals, plants and even other microorganisms.
Answer:
True
Explanation:
Cofactor is a biological term used in describing a form of a non-protein chemical compound. It is highly required in the biological operation. It is in two types, the Coenzymes and Prosthetic groups.
While the Prosthetic groups are well connected to an enzyme, the coenzymes on the other hand are conected to an enzyme loosely.
Hence, it is TRUE that Cofactors for some enzymes are not considered prosthetic groups because they are loosely held during the course of the action
Answer:
structure X is the substrate so the answer is A
Explanation:
As it is trying to fit in the enzymes active site
In asexual reproduction, one organism can produce other organisms. Asexual reproduction involves various kinds of cell division in which one organism produces one or more new organism that are identical to itself. Organisms reproduce asexually in many ways in prokaryotes, bacteria reproduce asexually by cell division. Some eukaryotes may also reproduce asexually by complex processes.
