Which statement about positive feedback regulation is accurate?

Biology
1 answer:
GenaCL600 [577]3 years ago
6 0

Answer:

Answer is B. Positive feedback regulation can generate an abrupt, all-or-none response in which the cell moves from ignoring a signal to responding to it very strongly.

Explanation:

Positive feedback can be described as an example of feedback, which is a natural mechanism that amplifies the action of a system.

It can be better be explained further, as a situation whereby the blood pressure decreases and the response of the body also makes or causes the blood pressure to decrease the more.

Other examples of a positive feedback also include blood clotting, ripening of fruits , uterus muscle contraction, resulting to the stretching of the uterus during pregnancy.

Answer:

Golgi apparatus and extracellular matrix

Explanation:

The Golgi complex lies at the heart of the secretory pathway and is responsible for modifying proteins and lipids, as well as sorting newly synthesized molecules to their correct destination. As a consequence of these important roles, any changes in its proteome can negatively affect its function and in turn lead to disease.

Disruption of specific transport steps between the endoplasmic reticulum (ER), Golgi complex, endosomal-lysosomal system and the plasma membrane all can have dramatic consequences on the cell, and increasingly defects in the molecular machinery regulating membrane traffic are being linked to hereditary diseases.

Any changes to the proteome of the Golgi complex would affect its homeostasis and consequently the flux of proteins trafficking through it.

One possible consequence of mutations in Golgi complex proteins is that they cause gross changes in the morphology of the entire organelle and protein mislocalization, which together result in functional problems such as impairment of glycosylation.

Genetic studies of humans and mice continue to highlight the nonredundant mechanical role of components in complexes that anchor cells to extracellular matrices. At the same time, recent data provide exciting insights into, critical roles of transcription factors in regulating differentiation and function of matrix-producing cells.

List and describe the events involved in the inition, elongation and termination of translation in eukaryotic cells
Illusion [34]

Answer:

Translation proceeds in three phases: Initiation: The ribosome assembles around the target mRNA. ... The ribosome then moves to the next mRNA codon to continue the process (translocation), creating an amino acid chain. Termination: When a stop codon is reached, the ribosome releases the polypeptide.

True or False. When paired with an immunosuppressant drug, saccharine (sugar) did not have immunosuppressant effects on rats.
Anastaziya [24]

The statement 'when paired with an immunosuppressant drug, saccharine (sugar) did not have immunosuppressant effects on rats' is FALSE. Saccharine is an artificial sweetener.

<h3>Immunosuppressant drugs and saccharine</h3>

Immunosuppressant drugs are a type of drug that exhibits a depressive effect o the immune system of the individual.

Immunosuppressant drugs include, for example, adalimumab, infliximab, calcineurin inhibitors, cyclosporine, etc.

Moreover, saccharin is an artificial sweetener that is 400 times as sweet as sucrose (sugar).
