What would MOST LIKELY occur if a plague killed most of the prey organisms within a once-healthy ecosystem? A. The number of con
sumers would increase. B. The number of scavengers would increase. C. The number of predators would decrease. D. The number of producers would decrease.
When using a microscope, generally magnification is higher and a ruler will not work unless you are using a very low power stereo microscope. When using a compound high power microscope an eyepiece reticle is used to make measurements.
Photosynthesis is the process by which photosynthetic organisms transform light energy into chemical energy
Photosynthesis is an oxidative reductive metabolic pathway in which water is oxidized and carbon dioxide is reduced to carbohydrates
Light reaction of photosynthesis is concerned with light dependent oxidation of water and synthesis of high energy compounds such as ATP and NADPH
All proteins and cofactors which involves in light reaction are present in thylakoid membrane hence light reaction of photosynthesis completed in thylakoid membrane
Transfer of electron and protons in thylakoid membrane is carried out by four protein complexes and two mobile electron carriers
Oxidation of one water molecule generates two electrons, two protons and one atom of oxygen
Transfer of one electron from Photosystem II (PSII) to Photosystem I (PSI) requires one photon and transfer of one electron from PSI to NADP+ requires one photon, thus transfer of two electrons from PSII to NADP+ requires four photons
Flow of two electrons from cytochrome b6f complex drives transportation of four protons from stroma to lumen
Thus oxidation of one water molecule establish gradient of 6 H+, gradient of 6 H+ drives synthesis of 2 ATP
Reduction of 1 NADP+ to NADPH requires two electrons, thus oxidation of one eater molecule generates 1 NADPH
Once the oppositely charged ions form, they are attracted by their positive and negative charges and form an ionic compound. Ionic bonds are also formed when there is a large electronegativity difference between two atoms.
