What is the function of each of these structures in the cell membrane? a) phospholipid bilayer b) peripheral protein c) integral protein d) glycolipid & glycoprotein e) cholesterol

Answers

Answer 1

Answer:

The correct answers are described in the Explanation section.

Explanation:

The function of the structures in the cell membrane are as follows:

a) phospholipid bilayer: comprised of fatty acids and alcohol, the phospholipid bilayer acts as a hydrophobic barrier to avoid the uncontrolled transport of molecules and ions.

b) peripheral protein: they are proteins present in the external surface of the cell membrane. This proteins form temporary bonds between the cells and other molecules, attaching and detaching at specific times.

c) integral protein: this proteins have one part of its structure in the surface and other part within the cell membrane. They have different roles, including: receptors, transporters, linkers, channels, among others.

d) glycolipid & glycoprotein: proteins that have carbohydrate-bearing portions  in its extracellular environment. They maintain the stability of the cell membrane and facilitate cellular recognition.

e) cholesterol: cholesterol structure helps to the packing of the phospholipids, which restricts the passage of the molecules.

Because molecules will move from one side to another to come to an equilibrium, or balance of concentration, the _________________________moves from side B to side A, so the water level on side A goes _____________________________.

Answers

Answer:

Water, up

Explanation:

In the process of movement water in the diffusion of water the net movement of water goes from higher concentration to the low concentration area. The movement of water  move form one side to other side until it reaches an equilibrium and the level of water on the other side goes up.

Hence, the water molecule will move from from side B to side A until it reaches equilibrium and the water level on side A goes up.

Answers

Answer:

Velocity is a speed while force is a push or pull.

Explanation:

Velocity refers to the speed of an object in a specific direction whereas force is a push or pull in order to move an object one place to another. When we apply force on an object, the object moves in the direction of force applied so this moving is known as velocity. The unit of velocity is meter/ second whereas unit of force is newton which is equal to kilogram meter / second square.

Which process helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II?
fertilization
independent assortment
crossing over
chromosome replication

Answers

Answer:

Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome .

The process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.

Crossing over, also known as recombination, is the interchange of genetic material between non-sister chromatids of homologous chromosomes.

This process (crossing over) occurs in Meiosis I, specifically during Prophase I.

Crossing over during Prophase I and the independent assortment of homologous chromosomes during Metaphase I represent meiotic processes that help to increase genetic variation in gamete (sex) cells.

In conclusion, the process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.

which part of thr mitochondrion does an electron transport chain occur?​

Answers

Answer:

Electron transport chain is the series of the cycle of the transfer of electrons from the one complex to other complex of the cycle. Both oxidation and redo reaction occurs in the electron transport chain.

The process of electron transport chain occurs in the inner mitochondrial membrane. All the complexes and the substrate of the cycle are embedded in the inner mitochondrial membrane. ATP is produced by this cycle located in the inner mitochondrial membrane.

f nitrogen and hydrogen combine in a combustion reaction, what would the product of the reaction be?

CH4 + 2O2 →
2 + 2H2O

Answers

Answer:

NH3

Explanation:

When hydrogen and nitrogen react it forms ammonia which is also as Haber's process

Remember, when working with combustion reactions the products are almost ALWAYS
CO2 + H2O.

Your equation should now be:

CH4 + 2 O2 -> CO2 + 2 H2O

Note: this equation is balanced

If we’re talking about combining Nitrogen and Hydrogen in a reaction, it would synthesize to form ammonia (NH3)

The chemical equation for that would be:

N2 + H2 -> NH3

Balanced chemical equation:

N2 + 3 H2 -> 2 NH3

(If you’re wondering where the 2’s come from in N2 and H2, it’s because they are known as diatomic elements.

Diatomic elements are:

Hydrogen
Oxygen
Bromine
Fluorine
Iodine
Nitrogen and
Chlorine

•To make it easier to memorize remember the acronym, HOBrFINCl.

•When these elements are seen individually in a chemical equation the 2 at the bottom (aka subscript) is placed.
