The correct answer is - Its electrons are used to form NADPH.

On receiving light energy, electrons are expelled from the reaction center of photosystem II. The expelled electrons finally reduces oxidized NADH⁺ to NADH. The oxidized reaction center of photosystem II split water into protons, electrons and oxygen. The electrons released from water reduces oxidized reaction center of photosystem II. Thus, oxidized reaction center of photosystem II gets back its expelled electrons. Therefore, electrons from water forms NADH.

The correct answer is option A, Its electrons are used to form glucose.

Reason -

In the light reaction phase of photosynthesis, the water gets broken into its constituent’s elements that are oxygen, H+ ions and free electrons. This process takes place in the thylakoid membrane in the presence of an enzyme. The released free electrons replace the loss of electron during the process light dependent reaction in the photosystem II.

Which of the following correctly rank the steps in erythrocyte glucose transport by GLUT1? I. Glucose binding results in a confo
3241004551 [841]

Answer:

Following are the correctly rank steps:  

1. The binding of glucose takes place with the transporter on one side of the membrane.  

2. The binding of glucose leads to a conformational change, which opens the site of binding on the contrary side of the membrane.  

3. The dissociation of glucose takes place.  

4. The transporter moves back to the beginning conformation.

You are doing an experiment involving antibiotic resistance in your study bacteria. This organism grows well on LB - Miller agar
KiRa [710]

Answer:

See the answer below

Explanation:

The stock solution of Gentamycin has a concentration of 5 mg/ml while each plate needs to contain 50 micrograms/ml of Gentamycin.

5 mg/ml = 5000 micrograms/ml

There is a need to dilute the stock antibiotic solution in order to arrive at 50 micrograms/ml. Using the dilution principle;

m1v1 = m2v2

5000 x 1 = 50 x v2

v2 = 5000/50 = 1000 ml

<em>Hence, in order to prepare 50 micrograms/ml, 1 ml of the stock Gentamycin should be taken and diluted with 999 ml of distilled sterilized water. 1 ml of the diluted Gentamycin will then be added to each agar plate while they are still in the molten form at a warm temperature.</em>
