describe the six functions of membrane proteins

Answers

Answer 1

Answer:

All enzymes are a type of protein. As a result, a membrane protein that is embedded into the membrane can sometimes be an enzyme, which may have its active site facing substances outside of the lipid bilayer.

These types of enzymatic membrane proteins can work in teams to carry out the steps in a particular metabolic pathway, for instance breaking down lactose into carbohydrate and then monosaccharides.

Membrane proteins can allow hydrophilic molecules to pass through the cell membrane. Transport membrane proteins come in many forms, and some require energy to change shape and actively move molecules and other substances across the cell membrane. They do this by releasing ATP to use as an energy source.

Anchorage: become points of attachment for the cytoskeleton and the extracellular matrix

Some membrane proteins can feature a binding site. These binding sites are characterized by specific shapes that match the shape of a chemical messenger. For example, these chemical messengers can be hormones.

When a hormone meets with the cell wall, it will connect with a receptor membrane protein that is embedded inside the cell wall. The hormone can change the receptor protein and cause a specific reaction, depending on the type of hormone or other substance, will take place within the cell.

Another important function of membrane proteins is in identification and recognition between cells. This particular function is useful in the immune system, as it helps the body to recognize foreign cells that may be causing infection, for instance. Glycoproteins are one type of membrane protein that can carry out cell recognition.

Adjacent cells may have membrane proteins that connect in a range of different junctions. Gap junctions and tight junctions.

This function helps cells to communicate with one another, and to transfer materials between one another.

Membrane proteins are important in the cytoskeleton, the system of filaments and fibers in the cytoplasm of a cell, and the extracellular matrix (ECM), which is the network of macromolecules found outside of cells, such as collagen, enzymes, and glycoproteins, to membrane proteins.

Attaching filaments or fibers in the cytoplasm found throughout the cell can help the cell to maintain its particular shape. It also keeps the location of membrane proteins stable.

Attaching membrane proteins to the extracellular matrix can help the ECM to mediate changes that occur in extracellular and intracellular environments.

Several diseases are linked to mutations within membrane proteins. One example is a mutation called V509A, found in the thyrotropin receptor, thyrotropin being a hormone secreted by the pituitary gland that regulates the production of thyroid hormones.

This mutation increases the activity of the thyrotropin receptor and leads to congenital hyperthyroidism, a condition that can cause changes in mood, sleep problems, and stomach problems.

Other diseases that are linked to mutations in membrane proteins include hereditary deafness, Charcot-Marie-Tooth disease, which damages the peripheral nerves outside the central nervous system, and Dejerine-Sottas syndrome, that affects a person’s ability to move.

What do you mean by biodiversity?

Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level.

Scientists often speak of three levels of diversity: species, genetic, and ecosystem diversity. In fact, these levels cannot be separated. Each is important, interacting with and influencing others. Changes at one level can cause changes at other levels.

Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can't even be seen by the eye.

How does a change in pH above or below optimal pH affect enzyme
function?

A. No change
B. Reaction happens faster
C. Enzyme dies
D. Enzyme denatures

Answers

Answer:

[tex]\boxed {\tt D. \ Enzyme \ denatures}[/tex]

Explanation:

Extreme temperatures or pH can denature enzymes.

Enzymes have a very special and specific shape that determines which substrate they can act on. If the pH changes too dramatically, then the peptide bonds holding the amino acids of the enzyme together break.

When the bonds break, the enzyme loses its shape and it cannot function anymore.

So, there is a change, the reaction doesn't happen faster or die. We can eliminate choices A, B, and C. The correct choice is D. enzyme denatures

A. Earth is the only planet that changes structure.

B. Earth is the only planet that turns around in space.

C. Earth is the only planet that is mostly covered with water.

D. Earth is the only planet that is mostly made from rocks.

Answer:

The correct answer is - option C. Earth is the only planet that is mostly covered with water.

Explanation:

Earth is the only planet in our solar system that has liquid water, and it covers 75% of the total surface of the planet that gives it a unique identity as the blue planet of the solar system.

There are some other differences as well like plate tectonics, atmosphere and life make earth totally different from other planets.

earth can support the survival of organisms.what is/are the factory/s that make/s earth habitable?

Answers

Answer:

The factors that make Earth support the survival of organisms are it's correct distance from the sun, the Earth is protected by solar radiation by it's magnetic field, stability of it's warm atmosphere, availability of some chemical composition that support life like oxygen, water, nitrogen e.t.c., proximity of the sun in allowing the passage and flow of water, the shape and size of the Earth as Rocky planet e.t.c.

Explanation:

Earth is the planets that support the survival of living organisms and this is because of the following factors that support the existence of life and these factors includeit's correct distance from the sun, the Earth is protected by solar radiation by it's magnetic field, stability of it's warm atmosphere, availability of some chemical composition that support life like oxygen, water, nitrogen e.t.c., proximity of the sun in allowing the passage and flow of water, the shape and size of the Earth as Rocky planet e.t.c.

It's correct distance from the sun makes it's to have stable temperature i.e not to hot and not too cold. With the temperature, living organisms can survive and live.

Earth is protected from solar radiation by ozone layer and it's magnetic field. This layer hinders the penetrations of some harmful Ray's it radiations that can damage it destroy living organisms.

It's allow water flow and water is essential for life . It is useful for plants for growth , photosynthesis and germination. Water is essential for animals because, it's aids digestion and metabolic processes.

Earth's atmosphere have right composition of chemicals that support life and these chemicals include oxygen, nitrogen, carbon, water e.t.c.

For example oxygen is important for respiration which releases energy to perform cellular activities.
