CH2O5 +603-6CO2 + 6H2O + energy isn't the evidence of conservation of mass in cellular respiration.
Option B
<h3><u>Explanation:</u></h3>
Law of conservation of mass states that mass can neither be created nor be destroyed. And this law holds good for all sorts of chemical reactions except the nuclear reactions.
In case of cellular respiration, one molecule of glucose reacts with 6 molecules of oxygen to produce 6 molecules of carbon dioxide and 6 molecules of water and energy. Now this energy that is produced isn't produced in expense of mass, but in expense of chemical bonds that are present in glucose molecules.
Also if we calculate the number of atoms on each side of the reaction, the number of atoms remain same as well as number of atoms of individual elements also remain same.
During the electron transport, chan energy stored in electrons is used to pump hydrogen protons from the mitochondrial matrix to the intermembrane space. The numbers of protons increase this creates a chemical gradient(because there is a higher concentration of ions) and an electrical gradient(because the intermembrane space becomes more positive than the matrix because of the protons-H⁺). Those protons need to flow towards the matrix for equilibrium to occur. As we know the inside membrane of the mitochondria has a reduced permeability. The main place where protons can diffuse is the ATP-synthase(a protein that turns ADP and inorganic phosphate into ATP). When protons pass through they release the energy necessary for this reaction to occur(ADP+H₃PO₄-->ATP+H₂O)
Answer:
Option (c).
Explanation:
The kin selection was first used by the Hamilton's and explains how this selection increases the frequency among the recipient and the actor and also explain the genetic relatedness among the family members.
The Hamilton's rule depends on the genetic relatedness r and the benefits obtained by the action to the recipient and the energy or cost used during the action. The selection is positive if the product of genetic relatedness and benefits is more than the cost.
Thus, the correct answer is option (c).
