Answer:
Hydrogen and electrons
Explanation:
Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) serve as reducing power during energy transfers. One NAD+ accepts one hydrogen ions and two electrons and becomes reduced into NADH. Likewise, FAD accepts two hydrogen ions and two electrons and is reduced into FADH2. Oxidation of NADH and FADH2 into NAD+ and FAD respectively releases both hydrogen ions and electrons.
For example, some of the energy of glucose released during glycolysis and Kreb's cycle is temporarily stored in the form of NADH and FADH2. Oxidation of NADH and FADH2 via electron transfer chain of mitochondria releases both electrons and hydrogen ions (protons). The protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient.
Answer:
B. an asteroid belt lies between them.
Explanation:
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets.
During evaporation the sun heats a large body of water causing water vapor. What vapor is a gas. Evaporation is also apart of the water cycle, which evaporation in an important tool in the water cycle.
Remember this:
- When water is heated it turns into a gas.
-When water gets to 0°c water freezes.
-When ice is heated, it turns into a liquid.
Answer:
The cell is eukaryotic because it contains mitochondria.
nucleus
