<u><em>NAD+ and H+ are not the same. </em></u>
NAD+ is an electron carrier. Reactions in metabolism oxidize food molecules and transfer those electrons (along with H+) to > NAD+ which is what forms NADH. Now, NADH is the reduced form of NAD+ and NAD+ is the oxidized form of NADH.
H+ on the other hand, is a proton. It is a hydrogen atom that lost it's electrons. So when you see NADH + H+, that means that the reaction removed 2 electrons and 2 H+ from the compound.
During the Quaternary Glaciation, ice sheets expanded, notably from out of Antarctica and Greenland.
The answer is D. -Antarctica
Answer: chlorophyll
Explanation: the green color compound present in the leaf is chlorophyll. Chlorophyll is a chemical or a molecule that is present within the chloroplast of the leaf.
This compound is responsible for the conversion of carbon dioxide and water with the help of light energy of the sun into sugars. And plant prepares its food through this chemical compound. This process is known as photosynthesis.
A positive ion is formed when an electron is removed from an atom until there are fewer elections than protons. A negative ion is formed when an atom gains electron until there are more electrons than protons
