Place the events of the light-dependent reactions of photosynthesis in the correct order. question 2 options: atp is formed as hydrogen ions move down their concentration gradient through the atp synthase molecule an electron passes down the electron transport chain and nadph is formed along the way water is split photons are absorbed by chlorophyll hydrogen ions are pumped against their concentration gradient

What is the next step in the process after a substrate enters the active site of an enzyme

Define the apical impulse and describe its normal location, size, and duration. which abnormal conditions may affect the location of the apical impulse? explain the mechanism producing normal first and second heart sounds. describe the effect of respiration on the heart sounds. describe the characteristics of the first heart sound and its intensity at the apex of the heart and at the base. describe the characteristics of the second heart sound and its intensity at the apex of the heart and at the base.

If you relate the doppler effect on sound to the color of light waves, a police car would be the color as it approaches and the color as it recedes away from the observer.
