Answer: The correct answer is D. ATP provides energy coupling between exergonic and endergonic reactions.
ATP hydrolysis is an exergonic reaction, as a large amount of energy is released when this molecule is hydrolyzed. ATP is converted into ADP ( adenosine diphosphate) and inorganic phosphate. The energy released in this reaction is utilized by the endergonic reactions ( which require energy) such as photosynthesis.
Thus, the central role that ATP in cellular metabolism is that it provides energy coupling between exergonic and endergonic reactions.
Answer: Option D.
The lub heart sound is due to the closing of atrioventricular valves.
Explanation:
Heart sounds are noises that are generated from beatings from heart and from blood that flows through it. The heart sound reflect the turbulence generated when the heart valves snap shut. Lub is the first heart sound also called S1 and it is caused by turbulence and closure of the atrioventricular valves(mitral and triscupid valves) at the start of systole. The second sound is the dub sound which caused by the closing of aortic and pulmonic valves at the end of systole.
Answer:
Cork is a natural cellular material of biological origin with an interesting and unique combination of properties. It has low density, buoyancy, very low permeability, low thermal coefficients, elasticity, and withstands large deformation without fracture under compression.
