Answer:
The correct answer is option A, that is, cytochrome c oxidase.
Explanation:
A sequence of complexes, which conduct electrons from electron donors to electron acceptors through redox reactions, that is, both oxidation and reduction reactions taking place simultaneously is termed as the electron transport chain. This conduction of electrons is further combined with the mediation of protons across a membrane.
Four membrane-bound complexes are present within the mitochondria, of these in complex IV or cytochrome c oxidase, the withdrawal of 4 electrons takes place from 4 molecules of cytochrome c, and is mediated towards the molecular oxygen, which further gives rise to 2 molecules of water. During the process, 8 H+ are withdrawn from the mitochondrial matrix, which contributes to the proton gradient.
The answer is; asexual reproduction
In specific, this type of asexual reproduction is called budding. In this type of reproduction, the offspring is completely identical to the parent and there is little room for variation as in the case of sexual reproduction. Other living organisms that exhibit this type of reproduction are yeast, bacteria, and protozoans.
Mapping and identification of the first mutations on autosomes responsible for Parkinson’s disease (PD) indisputably showed that PD may be hereditary. <span>All of the currently known PD forms are dominant or recessive, which means that they are linked with regions on autosomes (chromosomes other than sex chromosomes). The chromosomes can end up rearranging and there can be a part missing of the chromosome, or it was duplicated. That can also cause PD, which geneticist can see when they look at strands of DNA.</span>
Peyer's patches are lymphatic tissue patches that are located in the small intestine. The lymphatic system provides an immune response for the body, so if there was an infection of the Peyer's patches, the body's defense system in the small intestines, which would make the intestines more susceptible to cancer or infection.
Answer:
Positron emission tomography (PET)
Explanation:
Positron emission tomography (PET) consists of the measurement of the physiological function by inspecting the flow of the blood, metabolic functions, radiolabelled drugs, and neurotransmitters. PET provides quantitative analyses making it possible to monitor relative changes as time passes, keeping control of the progress of a disease or how the person reacts to a stimulus. To do it, the person receives a low quantity of a radioactive tracer into his/her organism via injection.
