What happened if we add normal saline instead of PBS during beta amylase extraction?

Answers

Answer:

Explanation:

Saline is the solution of water and NaCl does not provide the appropriate pH, so enzyme activity is lost, we cannot add saline instead of PBS during beta amylase extraction.

How saline water affects beta amylase extraction?

PBS (phosphate buffer solution) is a type of buffer that is suited for beta-amylase activity, which implies that when beta-amylase is extracted using buffer, the enzyme's chemical activity is kept.

When we utilize saline, which is a solution of water and NaCl, the pH of the solution is not acceptable, and the enzymes' chemical activity is destroyed.

As a result, for enzyme/protein extraction, we always employ a buffer solution, which maintains the ph for the proper functioning of an enzyme.

Therefore due to pH conditions enzyme lost activity, and normal saline water can not be used instead of PBS for extraction of beta-amylase.

What is mitochondria?

Mitochondria are cell organelles that generate the maximum of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).

The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).

The crista of mitochondria, formed by invaginations of the inner mitochondrial membrane, is where oxidative phosphorylation occurs.

Thus, the process name is oxidative phosphorylation.

A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.

B. Channel and carrier proteins are both types of facilitated transport.

C. Channel and carrier proteins can only move substances in one direction either into the cell or out of the cell.

D. Channel and carrier proteins always move substances from the side of the membrane with the highest concentration to the side with the lowest concentration.

Answers

Answer:

Explanation:

A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.

Channel and carrier proteins are both types of facilitated transport.

Facilitated diffusion is one of the ways of transporting molecules and is characterized by the use of proteins that are inserted in the plasma membrane, such as ion channels and carriers or permeases.

Ions, amino acids and monosaccharides, among many other molecules, cannot cross the plasma membrane, because they are polar or are very large in size.

So, for the cell to obtain or eliminate these substances, the presence of transporter proteins is necessary.

This diffusion is a type of passive transport, because it takes advantage of the concentration gradient of the molecules and does not waste energy.

Ion channels are integral tunnel-shaped proteins, selective for one, two, or three ions.

When a channel opens, ions flow under two principles: the concentration gradient and the electrochemical gradient.

Consequently, when an ion channel opens, the potential difference between the two compartments is altered.

Transmembrane proteins mediate the transport of molecules such as bicarbonate or large, polar, uncharged molecules such as glucose.

The transport through these proteins occurs in favor of the concentration gradient, and by a reversible conformational change of the proteins that allows the translocation of the molecule to the other side of the membrane.

This type of transport is always without energy expenditure and in favor of the electrochemical gradient, it occurs in the following way:

Uniport, a single molecule translocates in only one direction.

Simporte, two molecules that translocate in the same direction.

Therefore, we can conclude that channel and carrier proteins are both types of facilitated transport.

why is forcing the cell to increase the rate of the cell cycle lead to error in DNA replication

Answers

We tend to think of the process of DNA replication as this well laid out stoic process like a factory line. It isn't. The DNA doesn't lie in a straight line for the DNA polymerase to read and it is moving - not static. It is tangled and curved. First understand this is the molecular level. Things don't "think", bacteria don't make decisions, they have no neurons. Everything is a chemical reaction that very often depends on osmotic pressure of one concentration being stronger then another both inside of the cell and outside. Nothing is empty though even at that level there is a lot of "nothing".

Which statement is true regarding the transmission of sex-linked traits in a population?
O Males cannot carry recessive alleles for sex-linked traits.
O Males cannot express dominant alleles on the X chromosome.
O Males cannot express recessive alleles on the X chromosome.
O Males cannot pass alleles for sex-linked traits to their daughters.

Answers

Answer: none of the statements are true

Explanation: Males can have a recessive copy of a X-linked gene, and can pass that on in the X containing gamete and so pass it on to daughters, but not to male offspring. Males will express whichever allele, dominant or recessive that they carry.

Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2

Answers

Answer:

A 0.015M

Explanation:

Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:

Molarity (M) = mole (n) / volume (L)

Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.

We can calculate the number of moles of KCl in the solution by using the formula:

Mole = mass ÷ molar mass

Where atomic mass of; K = 39, Cl = 35.5

Molar Mass of KCl = 39 + 35.5

= 74.5g/mol.

Mole = 0.83g/74.5g/mol.

mole = 0.01114

Approximately, n = 0.011mol

Hence, molarity = 0.011mol/0.75L

Molarity = 0.0146

Molarity = 0.015M
