16. The light-dependent reactions of oxygenic photosynthesis has two pigment molecule photosystems. Photosystem II generates __________, while Photosystem I generates ____________. oxidizing power in the form of NADP+; the photosynthetic electron transport chain the photosynthetic electron transport chain; chemiosmosis chemiosmosis; reducing power in the form of NADPH the photosynthetic electron transport chain ; reducing power in the form of NADPH 17. During anoxygenic photosynthesis light causes the photosystem reaction center pigment molecule to release a high-energy electron that is passed through an electron transport chain and is accepted by ___________. the reaction center pigment molecule that released the electron ATP synthase to generate ATP hydrogen sulfide, H2S NADP+ to generate reducing power 18. The Calvin-Benson Cycle leads to the anabolic production of glucose by using energy and electrons conserved in the form of ___________. ATP and NADPH NADPH only ATP only 19. Many nutrient cycles are coupled and changes in one cycle will affect another. This means that a change in the amount of carbon dioxide fixed is intimately affected by the amount of __________ available in an ecosystem. hydrogen oxygen nitrogen methane 20. Why is bioremediation of some xenobiotics slower than bioremediation of crude oil and petroleum products? Because humans do not want to remediate the accumulation of xenobiotics. Many xenobiotic compounds are so toxic that bioremediation is not possible. Microorganisms have not evolved to degrade human-made xenobiotics. Xenobiotics were designed to inhibit microbial growth.

Transcript

00:01 In this question, we're asked which of the following events occurs during glycolysis.

00:05 So, colicis is going to be the first stage in the process of cell respiration.

00:11 In this stage, six carbon glucose will be converted into two molecules of three carbon pyruvate, and along with that we have the release of 2 atp.

00:20 And so the correct answer here is going to be that pyruvate is going to be made from glucose, as glucose is turned into two pyruvate.

00:36 And so that will be answer choice e...

Question
