What is cell membrane made up ?





Answers

The cell membrane is mainly composed of lipids. Moreover, the cell membrane also contains membrane proteins and carbohydrates.

The cell membrane:

The cell membrane is a cellular structure that separates the cell from its surrounding environment.

The cell membrane is mainly composed of lipids, i.e., phospholipids and cholesterol (steroids).

However, the cell membrane also contains membrane proteins (both integral as peripherical proteins) and carbohydrates (i.e., glycoproteins).

In conclusion, the cell membrane is mainly composed of lipids, although this structure also contains proteins and carbohydrates (glycoproteins).

Why is it that nitrogen is often a limiting plant nutrient, despite the fact that the atmosphere is 80% nitrogen gas (N2)

Answers

Nitrogen is a limiting plant nutrient because the bulk of the available nitrogen in the atmosphere is not usable by plants.

Plants are not able to make use of the nitrogen in the atmosphere directly. Atmospheric nitrogen needs to be converted into usable forms before it can be accessed by plants.

The conversion of atmospheric nitrogen to usable form by plants is known as nitrogen fixation and this is achievable by the activities of certain bacteria.

Answers

The eye has cones sensitive to colors associated with Red, green, and blue

according to the trichromatic theory of color vision.

The trichromatic theory of color vision states that the eyes can view only

three colors which are red, green and blue. This is made through the cones

which are light sensitive pigments in the eyes. The combination of their

wavelengths can be used to create other colors in the visible light spectrum.

The stated facts is the reason why Red, green, and blue is the most

appropriate choice in the list of options.

what are the four final cell types produced by oogenesis in the female

Answers

Answer:

Oogenesis in the female is the process that produces fertile eggs, ready for fertilisation by the male sperm. Each egg has only one of each of the 23 human chromosomes - normal body cells have a pair of each, having 46 chromosomes in total.

To produce egg cells, the process of oogenesis takes place in the female ovary. Progenitor cells divide through a cell division process called meoisis, which is also known as a reduction division.

Instead of one cell splitting into two identical cells, four cells are produced which have half the normal number of chromosomes - they are described as being haploid.

The four cells are all genetically different because the process of meiosis involves cross overs of the chromosomes during division, so mixing up the genes inherited from the woman's mother and the woman's father. This variation produces fitter offspring as it widens the genetic variation that is possible.Explanation:

What is the role of ATP in transport of materials

Answers

Answer:

Functions of ATP in cells

Explanation:

ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.

Answer:

The role of ATP in the transport of materials :-

To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.

Because they have a wide surface area to speed up absorption, root hair cells are designed to absorb water and mineral ions.

What is the role of root hair cells in plants?

Plants are anchored by root hairs that emerge from the surface of the soil and take up water and minerals.

Vascular tissue in the heart of the root transports food produced in the leaves to the root, while transporting water and minerals away from it.

Its main purposes include anchoring the plant, absorbing water and dissolved minerals and transferring them to the stem, as well as storing reserve food.

Water and nutrients are mostly taken up by root hairs from the rhizosphere.

Therefore, root hair cell have large surface area that enable the cell to carry out its function.

What happens to the membrane protein (gray) when it is activated by the signal molecules?

Answers

Answer:

The receptor protein that is embedded in the cellular membrane must accept the signal.

Explanation:

When it receives the signal this protein will then go through a conformational change. This will change the shape and how it interacts with the molecules around it. Different receptor protein will act in different ways.

Answer:

As their name implies, GPCRs interact with G proteins in the plasma membrane. When an external signaling molecule binds to a GPCR, it causes a conformational change in the GPCR. This change then triggers the interaction between the GPCR and a nearby G protein.

What happens to the membrane protein (gray) when it is activated by the signal molecules?

The membrane protein interacts with the nearby GPCR.
