Step by step
Solved in 2 steps
- Cancer cells can use NADH to make electrons flow in the electron transport chain. is this statement true or false?they said that oxygen radicals are reactive, and unsaturated fatty acids are reactive too. does it mean that unsaturated fatty acids are considered radicals? provide a factual evidence why is it true or why is it not trueThe electron transport system consists of a series of oxidations rather than one reaction. Why is this an importantfeature of energy capture?
- ATP Is Generated During Photosynthesis and ___________ .In photosynthesis, CO2 carbon atoms are transformed to glucose carbon atoms. (a) Are the CO2 carbon atoms being oxidized or reduced in this process? (b) Do the CO2 carbon atoms move to a higher or lower energy state in this process?For every three molecules of CO2 that are incorporated into carbohydrate during the Calvin cycle there is a net gain of one molecule of _____________.
- Many of the enzymes involved in photosynthesis aid in chemical reactions that remove electrons from the oxygen atoms in water and transfer these electrons to the carbon atoms in carbon dioxide. In these reactions, which is the reducing agent and which is the oxidizing agent? Explain why you have chosen that. not just simply giving the answer. thanksH2S oxidation was one of the earliest mechanisms of photosynthesis on the ancient Earth. This mechanism requires less energy input than H2O oxidation. Suggest a reason why this major shift in electron source occurred.In a hypothetical situation, hydrogen sulfide is an additional electron carrier in the ETC. Everything else remains the same. Hypothesize where in the ETC would hydrogen sulfide end up functioning as an electron carrier and why?
- true or false All living photosynthetic organisms are capable of photosynthesis but not respiration.they said that oxygen radicals are reactive, and unsaturated fatty acids are reactive too. does it mean that unsaturated fatty acids are considered radicals? this statement is false, state a logical reasoning whyShow a diagram of electron transport chain in cellular respiration and highlight that phase in the diagram where oxygen plays an important role. Briefly describe that role of oxygen in respiration.
