The answer is D because the volcano cause that to happen
Answer:
b. They are carried throughout the body in the bloodstream, and each hormone affects target cells that have receptors for it.
Explanation:
Hormones are secreted by hormonal glands after they get signals to secrete or release the hormone. Then these hormones are carried by the bloodstream to their destination. Each hormone has its target organ or tissue which do not response to other hormones because it the cells in those tissue have specific receptor which binds to specific hormones.
For example, luteinizing hormone in male is produced by the pituitary gland which reach to the testis through blood and influence the Leydig cell to release testosterone. So Leydig cells have receptors for LH not for insulin hormone so it binds specifically to LH hormone. So the correct answer is b.
Chemiosmosis is the diffusion of diffusion of hydrogen ions (protons) across a biological membrane via ATP synthetase (a transport protein) due to a proton gradient the forms on the other side of the membrane.
Chemiosmosis is one of the processes by which ATP is synthesized. In Eukaryotes, it take place in the mitochondria during cellular respiration and in the chloroplast during photosynthesis.
The process is called chemiosmosis because the chemical ions move from an area of higher concentration to an area of lower concentration through a semi-permeable membrane, just like water molecules.
Answer:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Explanation:
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration
Almost all chemical reactions in life process occur in solutions with water.
