Answer:
Electron transfer to from cytochrome c to molecular Oxygen in the process of oxidative phosphorylation
Explanation:
Cytochrome c is a protein which is involved in the electron transport chain for the production of ATP molecules during then process of respiration. It a soluble protein found in the intermembrane space of the mitochondria. It receives electrons from ubiquinone at Complex III of the electron transport chain and transfers this electron to molecular oxygen through its interaction with complex IV or cytochrome c oxidase, reducing molecular oxygen to water.
If the interaction of cytochrome c with cytochrome c oxidase is inhibited, the process of elctron transfer to oxygen will be inhibited and, so ATP synthesis will cease.
Ultimately, respiration will be inhibited resulting in death of the organism. For example, cyanide inhibits cytochrome c oxidase resulting in death of the organism poisoned with cyanide.
They do not influence the salinity level in their environment, they maintain the salinity in their body. If they don't, osmosis will cause their cells to shrink due to the fact that the salinity in the cell is lower than outside the cell. This will make water leave the cells. So they need to get rid of excess salt all the time. Freshwater fish need to retain the salt in their bodies, otherwise the opposite will happen. Salinity level in the cell is higher than outside the cell and this causes influx of water which will make the cell build up turgor pressure. Ultimately they will explode. So fishes in both environments adapted to deal with osmosis.
Answer:
A
Explanation:
All living organisms pass on or transfer their genetic material to their offsprings. However, this transfer of genes occurs through the process of reproduction (sexual or asexual). Reproduction may (in case of sexual) or may not (in case of asexual) ensure genetic variation among species.
Eukaryotes that undergo sexual reproduction increase genetic variation among their species by undergoing Crossing-over (exchange of chromosomal segment between non-sister chromatids of homologous chromosomes) during meiosis or gamete formation. This process of transferring genetic material directly from parents to offsprings is called VERTICAL GENE TRANSFER, and only sexual-reproducing eukaryotes ensure genetic variation through this process.
On the other hand, prokaryotic organisms cannot undergo sexual reproduction, they undergo asexual reproduction instead and asexual reproduction does not guarantee genetic variation since identical daughter cells as the parents are produced from the process. However, to promote genetic variation among their species, they employ the processes of transformation, transduction and conjugation which are all forms of HORIZONTAL GENE TRANSFER because it involves transfer of genetic material from one cell (donor) to another (recipient) which do not have the parent-offspring relationship.
