Is enzyme activity a form of cell regulation

Biology

sergejj [24]2 years ago

A critical function of proteins is their activity as enzymes, which are needed to catalyze almost all biological reactions. Regulation of enzyme activity thus plays a key role in governing cell behavior.

Enzymes can be regulated by other molecules that either increase or reduce their activity. Molecules that increase the activity of an enzyme are called activators, while molecules that decrease the activity of an enzyme are called inhibitors.

Answer:

Because enzymes guide and regulate the metabolism of a cell, they tend to be carefully controlled. In this article, we'll take a look at factors that can affect or control enzyme activity. These include pH and temperature (discussed in the active site article), as well as: Regulatory molecules.

What evidence is there that the endangered species act is causing harm to species????
Juliette [100K]

Answer:

There is strong and increasing evidence the Endangered Species Act is causing widespread harm to the species it is supposed to protect-to the extent the Act may be doing more harm than good. The Act makes otherwise normal and legal forms of land and resource use illegal, such as farming, home building and cutting timber. The Endangered Species Act’s severe penalties-$100,000 and/or 1 year in jail for harming a single species or even unoccupied habitat that is deemed suitable-turn species in to liabilities. As a result, landowners seek to reduce their liabilities in a number of ways.

1. This scene is in British Columbia's Mount Robson Provincial Park.
solniwko [45]

There are four environments on Earth that are called spheres: hydrosphere, lithosphere, atmosphere, and biosphere.

<h3>Features associated with each of Earth's four spheres.</h3>

<h3>Hydrosphere </h3>

It is the set of all the water on the planet, including those that form clouds.

<h3>Lithosphere</h3>

The continuous part of our planet, made up of rocks and soil. The most superficial part is called the earth's crust.

<h3>Atmosphere</h3>

It is the gaseous sphere that surrounds our planet, composed mainly of gas oxygen and gas.

<h3>Biosphere </h3>

It is the part of our planet that can support life

<h3>Internal processes</h3>

The atmosphere and hydrosphere are the main regulators of the planet's climate. Without both, the temperature changes would be very sudden: at night it would drop to minus 150°C and during the day above 100°C, making life on Earth difficult.

With this information, we can conclude that the spheres of the earth, support life, and make the planet earth unique.

Which phrases describe what the rock cycle shows? Check all that apply.
Sonja [21]

Answer:

How rocks change from one type to another and which processes are involved in rock changes.

Explanation:

We know that there are three types of major rocks. Those are: igneous, sedimentary, and metamorphic. The rock cycle describes how the three major rock types convert from one to another.

Changing in rocks happens as a result of natural processes that are taking place all the time. Most of the changes happen very slowly. Rocks that are in the deep within the Earth are right now becoming other types of rocks. Rocks at the surface are lying in place before they are next exposed to a process that will change them to another rock. Even at the surface, we may not notice the changes in the rocks.

Along with this, a rock cycle describes those process which involves in this rocks transformation process. It represents various environmental factors that are related to the change of the rock from one to another.
