The right answer is 2HgO → 2Hg + O2
Balancing a balance equation consists of finding the right stoichiometric coefficients. These coefficients (placed in front of each molecule) balance the number of each of the different atoms involved during a chemical reaction.
In this reaction, we find on both sides the same number of atoms: two oxygen atoms and two atoms of mercury.
As your body gets older, it is less able to produce vital nutrients naturally, so it is recommended that adults take multi vitamins, to help offset the loss in vitamins and minerals.
Cellular respiration is the cellular process that begins with the breakdown of organic compounds (such as glucose) and continues with turning the resulting pyruvic acid <span>into a waste product and two molecules of ATP.</span>
Answer:
John Stephen Jones states that in evolution it is necessary to have into account three factors: natural selection, mutation, and random variation.
Explanation:
These three mechanisms influence evolution and they are responsible for generating phenotypic diversity that is observed in humans.
I recommend to read his article (chapter book):
Jones, JS. (2012). Is Human Evolution Over?. In Evolution 2.0 (pp. 167-176). Springer, Berlin, Heidelberg.
Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate. This a an early reaction in the glycolysis pathway that is a regulatory step in the pathway. An increase int he amount of ATP in the cell might cause decrease in the amount of phosphofructokinase enzyme by a process called feedback inhibition. Glycolysis process is regulated at various steps in which conversion of fructose 6-phosphate to fructose 1,6-bisphosphate is one of the regulatory step.
Answer: In the presence of oxygen, an increase in the amount of ATP in a cell would be expected to INHIBIT THE PHOSPHOFRUCTOKINASE ENZYME AND SLOWS THE RATE OF GLYCOLYSIS.
