The weight of cholesterol is 0.6 g.

Here use the concept of molarity.

<h3>What is molarity?</h3>

The amount of a substance in a specific volume of solution is known as its molarity (M). The moles of a solute per liter of a solution is known as molarity.

Molarity = no. of moles/volume (in L)

<h3>Calculation:</h3>

Given,

Molarity, M = 5.0 mM = 5 × 10⁻³ M

Volume, V = 315 mL = 315 × 10⁻³ L

To calculate,

Weight of cholesterol =?

We know that,

Molecular mass of cholesterol, C₂₇H₄₆O = 386

No. of moles = weight/ molecular mass

The formula is modified as,

Molarity = weight of cholesterol/ (molecular mass) (Volume)

Put the values in the formula,

5 × 10⁻³ = weight of cholesterol/ (386) (315 × 10⁻³)

Weight of cholesterol = 5 × 10⁻³ (386) (315 × 10⁻³)

= 0.6 g

Hence, the weight of cholesterol is 0.6 g.

In proteins, secondary, tertiary, and quaternary levels of structure depend on the primary structure.

Fittoniya [83]

Answer:b. Amino acid sequence, hydrogen bonding between backbone groups, the overall shape of a single polypeptide, and combinations of tertiary structures.

Explanation: Primary structure is the amino acid sequence in the polypeptide chain. When the sequence is altered due to mutation it can lead to formation of entirely new amino acid sequence.

Secondary structure could be the helical structure or the Beta pleated sheet. It is form from the interaction of atom that are backbones.It is the hydrogen bond between amino Hydrogen and carboxyl oxygen atom in the backbones

Tertiary structure- Overall structure of polypeptide. It result from interaction of the R groups amino acids. It gives the shape of the polypeptide.

Quantenary- Are protein made up of multiple polypeptide chain. This chain are also called subunit. It is the combination of all tertiary structures given rise to a functional protein.

What is considered the first stage of the cell cycle?

kirill115 [55]

Answer:

The first stage is the Interface.

Explanation:

There are primarily two main stages in a cell cycle; but the first stage is the interface. This is a stage in which a cell grows and also replicates its DNA.

It can be said to be the longest phase of the cell cycle. During this phase the cell growth reaches its maximum size, replicates its DNA, prepares for cell division, and also performs it very cellular functions.

This stage has three parts which include: G1, G2 and S phases.

Some cells do not need to divide to exit the cell cycle. These cells can exit the cell cycle permanently. Example is a neurons, they may also exit the cell cycle temporarily. These cells are said to be in G0 which is not a stage of the cell cycle.

Fed [463]

1. There would be an uncoupling of proton translocation and ATP synthesis. 2. ATP synthase would remain sensitive to Fo proton conduction inhibitors.

Adenosine di phosphate (ADP) and inorganic phosphate are used to create the energy storage molecule adenosine triphosphate (ATP) by a protein called ATP synthase (Pi). It is categorized as a ligase since it modifies ADP by forming a P-O link (phosphodiester bond).

A molecular device called ATP synthase. Energy-wise, the production of ATP from ADP and Pi is undesirable, and the process would typically go the other way.

A proton (H+) concentration gradient across the inner mitochondrial membrane in eukaryotes or the plasma membrane in bacteria drives this reaction forward by coupling ATP synthesis during cellular respiration to the gradient.
