Answer:
- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.
- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.
Explanation:
Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.
The two macro molecules contained in the salad with the lettuce, the eggs, also the bread crumbs and some olive oil is the protein and carbohydrates. The protein can help one person to grow and repair one's injury or wounds. While the carbohydrates as every one know, it provides the human's body the energy.
Answer:
they all have different charges
protons-positive
neutrons-neutral
electrons-negative
Interphase is the period of the cell cycle where the cell is actually growing, developing, and carrying out cellular processes. Essentially, interphase is when the cell is busy being a cell. It grows, synthesizes proteins, replicates its DNA, and so on and so forth.
<span>Mitosis is only the small portion of the cell cycle when it is dividing into two new cells. The rest of the time (interphase), the cell is performing its various functions.</span>
