Answer:
With a foundation of anatomy and physiology, you will have the building blocks to make the proper decisions and provide accurate and quality care. Of course, the study of anatomy and physiology is not static. New innovations in science and medicine change our understanding of the human body all the time.
Answer and Explanation:
Hydrogen ions in the thylakoid space form an electrochemical gradient because of the difference in the concentration of protons (H+) and the difference in the charge across the membrane that they create. This potential energy is stored as chemical energy in ATP through chemiosmosis. The hydrogen ions are allowed to pass through the thylakoid membrane through an embedded protein complex called ATP synthase. Energy from the electron fuels membrane pumps that actively move hydrogen ions against their concentration gradient from the stroma into the thylakoid space. The photon causes an electron in the chlorophyll to become excited.
Answer:
The mass number (symbol A, from the German word Atomgewicht [atomic weight]),[1] also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It is approximately equal to the atomic (also known as isotopic) mass of the atom expressed in atomic mass units. Since protons and neutrons are both baryons, the mass number A is identical with the baryon number B as of the nucleus as of the whole atom or ion. The mass number is different for each different isotope of a chemical element. Hence, the difference between the mass number and the atomic number Z gives the number of neutrons (N) in a given nucleus: N = A − Z.[2]
The mass number is written either after the element name or as a superscript to the left of an element's symbol. For example, the most common isotope of carbon is carbon-12, or 12
C
, which has 6 protons and 6 neutrons. The full isotope symbol would also have the atomic number (Z) as a subscript to the left of the element symbol directly below the mass number: 12
6C
.[3]
