Chantal was eating raisins and a few of them fell into her glass of drinking water. She finished eating the rest of the raisins.

When she went to dump out the water in her glass, she observed that the raisins had become swollen. Why would this have happened? A. The water content from the raisins moved into the glass of water. B. The water in the glass entered the raisins. C. The grapes used for making the raisins weren’t properly dried. D. The raisins were bad-quality raisins and therefore were swollen.

B is the answer. Dry raisins swell up because they undergo Endosmosis. When a rasin is put in water then the water passes through the semipermeable membrane

Answer:

Option B, The water in the glass entered the raisins

Explanation:

The concentration of water with in the resin is much lower than that of the glass of drinking water. Due to this difference in concentration, a concentration gradient is established which forces the water to move from region of high concentration (i.e glass) to the region of low concentration (i.e with in the resin) thereby causing the resins to swell.

Hence, option B is correct.

What is meant by the EA of a reaction? How do enzymes affect the EA and the DG of a reaction?
zepelin [54]

Answer:

Activation energy may be defined as the minimum amount of the energy required to convert the substrate into the product. The higher the activation energy of a reaction, the slower the speed of a reaction.

The enzymes decreases the activation energy of the reaction and increases the effective collision between the substrate. The enzymes does not change the DG (delta G) or free energy of the reaction. The enzymes maintain the equilibrium of the reaction by increasing the equal amount of the forward and backward rate of the reaction.

Arrange the sequence of events for the overall mitochondrial respiratory assembly in the correct order.
kotykmax [81]

Answer:

Option D, 4,2,1, 3

Explanation:

The mitochondrial respiratory chain (MRC) comprises of four membrane bound complexes and it involves the following steps

a) RC complexes (RCC) I and II reduces the RC’s equivalent where RCCI i.e receives electron from the NADH.  

b) These electrons are then transferred to the flavin mononucleotide factor and then passed on to the Fe-S embedded cluster .

c) These electron reduces the coenzyme Q  to ubiquinol  

d) With in the inner mitochondrial membrane (IMM), protons are trans located from IMM to the  intermembrane space (IMS)

e) RC complex II then transfer electron from succinate to the cofactor FAD

f) From FAD proton are transferred to the FeS cluster and on the other hand electron move from QH2 to the RC complex III

g) This RC complex III give its electrons to the cytochrome and they are further passes on to the RC complex IV

h) With four redox centers, the terminal RC complex translocate protein by using energy produced in electron transfer thereby converting oxygen into water.

Hence, the correct option is D
