<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.
The larger and atom, the lower the nuclear attraction charge, <span>Therefore similarly the longer the bond, the attraction decreases</span>
- is a protein in metabolic reaction
- lowers activation energy
- is not changed during reaction
The correct option is C.
Plasmodesmata are microscopic channels which are found in plants and some algae, these channels transverse the cell wall of plant cells and enable transportation and communication among cells. Plasmodesmata allow molecules to move directly from one cell to another cell.
Answer:
The paraphrase consists in saying with simpler words and with less technical words those obtained from a text. In this way, it facilitates its understanding, because the original information extracted is expressed in a simpler way.
The correct way to paraphrase is 2. Every organism must acquire and use energy to build new structures, repair old ones, and reproduce
Explanation:
That option is referring to nutrition, which is the process by which nutrients contained in food meet the needs of cells and allow the proper development of organs. For example, certain organs such as the liver, brain, heart and kidneys, in normal conditions account for 60-70% of total energy expenditure of the organism, to which we must add the energy used in the synthesis and in the new tissue formation
