In exothermic reactions, the products have higher energy than the reactants, and in endothermic reactions, the reactants have higher energy than the products.
Answer:
B. glucose – NADH – electron transport – O2
Explanation:
This is the sequence from glycolysis in which glucose molecules are split down to pyruvate, to oxidative phosphorylation.
During this process the electrons are released from glucose molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .
The makes the carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .
The electrons from above are transferred in hydrogen atoms to matrix by these co-enzymes.Where the H is split to electrons and protons.
The electrons for the ETC, produce the PMF for transporting protons into the intramembrane space.
The concentration of protons generated the electrochemical gradients which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.
The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.
Answer:
It shows that biodervasity is important for sustainable ecosystem for existence of the earth.
.Biodervasity ensures that each specie has a role to play in an ecosystem irrespective of the size.)
The story also shows that plant species have different medicinal purposes,and without plants human will not be able to get the needed medicines.
.
Explanation:
Bathroom cleaner would have the highest pH because it is an alkaline substance (pH more than 7) whereas distilled water is around pH 7 and lemon juice and vinegar are acids (pH less than 7).
Hope this helps!
They occur years apart, and the glacier theories is from research and just a theory..but the bible account of the flood is more a story instead of research and science.
