Which of these is a receptor molecule? A. cell membrane with an integral molecule marked B. There is a specific recess in this m
olecule on the extracellular side. C. A molecule in the intracellular fluid, whose shape is identical to this recess, is marked A. D. Letter C marks a molecule connected to molecule B and is located in the cytoplasm. E. Letter D marks a molecule in the cytoplasm, near molecule C. F. Letter E marks a molecule in the cytoplasm located below molecule D.
Receptor may be defined as the molecule to which the ligands or the signalling molecule binds. The binding of the molecules with its receptor helps in initiating the signalling cascade of the body.
The molecule that are marked B can acts as receptor because the receptor may present on the cell membrane or in the cytosol or in the nucleus. The B molecule shows the recess marked with the other molecule.
Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
It removes H2O from the atmosphere during glycolysis. Cellular respiration is when the plant or animal takes the nutrients it gets and converts it into energy. This example is closest to the idea of cellular respiration because it takes the water and converts it during the process of glycolysis
