B) it involves a chemical reaction.
Breathing is a part of physiologicalrespiration and functions to bring oxygen into the lungs and expel carbon dioxide. Cellular respiration is a chemical process by which energy is obtained within individual cells from biomolecules like glucose.
The ribosome, since all organisms need to synthesize proteins.
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation, especially the Earth. Remote sensing is used in numerous fields, including geography, land surveying and most Earth Science disciplines (for example, hydrology, ecology, meteorology, oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications.
Answer:
Option D.
Explanation:
An integral membrane protein is a type of membrane protein that is permanently attached to the biological membrane, including transmembrane proteins. Insulin receptor, epinephrine receptor, growth factor receptor and ryanodine channel are receptors/ channels which implies its presence on the cell membrane for signal from binding ligand to be translocated into the cell through a signalling cascade. Glucocorticoid is an lipophilic signalling molecule which can pass through the cell surface membrane (due to its lipophilic characteristic that enables it to pass through the hydrophobic core of the phospholipid bilayer) and acts on its receptor in the cell cytosol. Hence the glucocorticoid receptor is not on the cell surface membrane and is thus not an integral membrane protein.
I think c is the correct option...
