<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

$\huge\boxed{Option A}$

<h2>_____________________________________</h2><h2>Mutations:</h2>

Mutations are the changes produced in the nucleotide sequence of the genome.

There are four main types of mutations

Substitution

Insertion

Deletion

Duplication.

<h2>_____________________________________</h2><h3>DELETION:</h3>

A small segment of chromosome mat be missing. This condition is known as deletion.

For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.

<h2>_____________________________________</h2><h3>DUPLICATION:</h3>

In this condition, a part of chromosome present in exec ess to the normal chromosome.

For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.

<h2>_____________________________________</h2><h3>SUBSTITUTION MUTATION:</h3>

Substitution is a type of mutation where one base pair is replaced by a different base pair.

For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.

<h3>INSERTION MUTATION:</h3>

In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.

For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.

Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid.

In the first 2.5 hours after a radical neck dissection, 40 ml of medium-red, bloody fluid is obtained from the client's drainage

cluponka [151]

The nurse should assess the patient vital sign and notify the healthcare provider. For 2.5 hour after neck dissection, production of 40ml by the drainage is a bit excessive. There might be a bleeding in the site of operation that becomes the source of the drainage. Change dressing will not do anything. Applying pressure can be done if the site of bleeding is known.

In chloroplasts, ATP is synthesized from ADP plus inorganic phosphate (Pi) in a reaction catalyzed by ATP synthase molecules tha

garik1379 [7]

Explanation:

<em>Complete Question:</em>

<em>A. Blocking electron flow from one carrier to the next in the electron transport chains blocks formation of a proton gradient in the thylakoid. </em>

<em>B. Increasing the proton concentration difference across the thylakoid membrane is not associated with a parallel increase in the rate of ATP synthesis. </em>

<em>C. No ATP is synthesized when channel proteins that allow the free passage of protons are inserted into the thylakoid membrane. </em>

<em>D. No ATP is synthesized while the Calvin cycle is synthesizing carbohydrates and using ATP and NADPH at a high rate. </em>

Correct: C. No ATP is synthesized when channel proteins that allow the free passage of protons are inserted into the thylakoid membrane.

Photophosphorylation describes a process in which the H+ made in previous steps of photosynthesis, and free electrons are used to obtain energy stored as ATP; in the electron transport chain move down the chain the energy they release is used in pumping protons out of the thykaloid space.

The high concentration of H+ from photolysis, outside the leads to increased H+ concentration within the thykaloid space, due to its high permeability. This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow into the stroma through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP and inorganic phosphate, Pi. NAD+ functions as the terminal electron acceptor and is reduced to NADPH.

Thus:

a H+ concentration gradient is required for oxidative phosphorylation in the electron transport chain of the chloroplast, and thus the production of ATP
the H+ ion gradient must favor the flow of electrons into the stroma

The free flow of H+ disrupts the gradient, and H+ cannot flow into ATP synthase to produce ATP.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

The chloroplast is a membrane bound organelle found in plants. It contains several invaginations of a plasma membrane called the thylakoid membrane. This contains chlorophyll pigments, in stacks called granum, while the internal spaces of the organelle are called the lumen. Liquid surrounds the granum, forming the stroma.

During the light reaction:

Light is absorbed by pigments in phosystem II (PSII). This energy is transferred among pigments til it gets to the reaction center, and is transferred to P680; this promotes an electron to a higher energy level where it then goes to an acceptor molecule.
Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent.
the electron moves down an electron transport chain (to PS I)where it experiences continuous energy loss. This energy fuels the pumping of H+ from the stroma to thykaloid, leading to the formation of a gradient. The H+ move along their gradient and cross through ATP synthase, into the the stroma.
ATP synthase converts ADP and Pi to the energy storage molecule ATP.
The electron gets to photosystem I where it goes to pigments at P700. It absorbs light energy, the electron is promoted to a higher energy level, and passed to an electron acceptor. This leaves a space for another electron which is then replaced by one from photosystem II.
in the ETC, the molecule NADP is reduced to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.
