Answer:

"Proton decreases" would be the right approach.

Explanation:

The Kreb cycle or system plays a key role throughout a matrix of mitochondria. 3 NADH, 2 FADH2 as well as 1 ATP are synthesized.
Whenever the Kreb process has been halted, the acetyl CoA throughout the Kreb cycle has not been used. Pyruvate doesn't at all, disintegrate via acetyl CoA. Therefore in cells, pyruvate accumulates.
Unless the Kreb loop is halted, therefore the concentration of NADH and FADH2 declines.

Thus, they aren't used for the transportation chain of electrons. This is also why protons have not been discovered to be injected towards intermembrane space.

Which of the following is not an effect of complement activation? Select one: Interference with viral replication Increased phag

Nostrana [21]

Answer:

The correct answer is "Interference with viral replication".

Explanation:

The complement system is an essential part of the immune system that involves the activation of a series of proteins that act as a cascade and result in the development of inflammatory responses that help to fight infections. There are multiple effects of complement activation, however interference with viral replication is not one of them. The molecules that are able to interfere with viral replication are called interferons, and they synthesis and activation are not related with complement activation.

Discuss why emerging diseases are appearing in industrialized countries.

Andrew [12]

Answer:

The correct answer is "For different reasons, including: pathogens developed resistance, people traveling much more frequently and practices of terrorism".

Explanation:

Emerging diseases are infectious diseases that are new to a region, or that remerge from a place that were believed to be eradicated. For different reasons emerging diseases are appearing in industrialized countries. One is that pathogens may have developed resistance to the treatments, as they may evolved naturally or it was driven by overuse of antibiotics. Other is that people are traveling much more frequently than in the past, which helps pathogens from distance places to reach industrialized areas. Also, terrorism practices is a cause of introducing pathogens deliberately to a new place.
