1. to repair damaged cells
Answer:
A. whether the glycoproteins or capsid proteins on its surface recognize those of the host cells.
Explanation:
Virus has different surface proteins that are recognized by the receptors present on its host cell. The range of a virus is determined by the recognition of these proteins by the host cell.
The interaction between the receptor on the host cell and surface proteins on the viral capsid is important for viral genome entry in the host cell and to determine the range of the host cells.
If the surface protein of the virus is not able to bind to the receptor on any cell then the virus can not infect the cell. For example, the HIV virus infects only those cell which have CD4 receptors. So the right answer is A.
The enzyme will be transported to either the cytoplasm or the mitochondria to perform the functions.
<h3><u>Explanation:</u></h3>
Cellular respiration is the process by which a living cell burns nutrients like glucose, fats, or even proteins to produce energy molecules namely ATP to perform its daily works. This cellular respiration, which is mainly aerobic, takes place both in cytoplasm and mitochondria.
The glycolysis part of the cellular respiration takes place in the cytoplasm. The enzymes that take part in the glycolysis cycle reaches to cytoplasm from ribosome to perform.
But both the Kreb's Cycle and the Electron Transport chain take place in mitochondria. Kreb's Cycle takes place in mitochondria matrix and ETC takes place in inner mitochondrial membrane. Although ETC isn't a enzymatic process, Kreb's Cycle is fully enzymatic and the enzymes reaches from ribosomes inside mitochondria by transporters.
