[00:23:21]Okay.

[00:23:27]Do I B6FT waterl manganese chlorine.

[00:24:13]system. Most important H2 as you know that H+ plus elect more body structure.

[00:25:26]body.

[00:25:39]So already system H+ system deduct Hello.

[00:26:33]Hello.

[00:26:55]F0 F not by CF0 CF1 Finch.

[00:27:02]CF F1 chloroplast CF chloroplast F1 CF1 CF CF18 PH2 PH1 H+ Yes, correct.

[00:27:54]H+.

[00:28:01]So when H+ will increase PH will fall.

[00:28:04]So that next light reaction and photochemical phase include light reaction and photochemical phase include light reaction and photochemical phase include light reaction and photochemical phase include Don't be confused.

[00:28:42]Dear brothers, confus light reaction or photochemical phase system.

[00:29:09]ATP.

[00:29:11]All of the above.

[00:29:15]Correct.

[00:29:31]Next question number nine.

[00:29:34]Where water splitting complex associated with the photostorm 2 is situated aid.

[00:29:52]photo system 2.

[00:29:56]System one2 inner side of chloroplast outer membrane inner side of thyloid membrane outer inner side of chloroplast BJ system two splitting photos system two side water split 2G we know but question is asking about can which side of the thyoid membrane in the outer side or the inner side B will be correct side in the inner side of the membrane correct ready question which of the following is incorrect about cyclic photoporation cyclic photo incorrect cyclic only photo system one participated BJ cyclic photo hospitalization only system one is involved correct it occurs only light of wave length beyond 68 nome is available for excitation only synthesis of ATP occurs cyclic ATP synthesis of NADP also occur incorrect System D will be correct answer D will be correct answer here. Next question number 11 you have the process for which manganesees and chloride ions are required. Who process manganese chloride of water for transfer of H+ to NADP?

[00:32:27]A baron number question joy cockroach in cyclic photospation which one of the following is formed.

[00:32:38]Cyclic photo.

[00:33:06]The only sole product of cyclic photos is ATP. No NADPH and oxygen. No NAD oxygen. No, the answer will be A.

[00:33:18]A correct.

[00:33:28]If light is available for a given duration and then again made unavailable the biosynthetic process reaction.

[00:33:49]Continue for long duration. Now continue for unlimited time. Now continue for short duration. I will stop immediately.

[00:33:58]So what will be the correct answer of question number 13? I'm waiting for your answer.

[00:34:05]Question number 13 and again unavailable obviously continue for a short duration only continue for a short duration.

[00:34:19]Answer.

[00:34:21]Continue for a short duration.

[00:34:31]Clear. Okay.cess The biosynthetic process will continue for a short duration until the reserve ATP and NADPH is completely consumed.

[00:35:01]See next question number 14.

[00:35:05]Reduction process of Kelvin cycle requires how many ATPs for reduction of one molecule of CO reduction charge?

[00:35:13]Kelvin cycle answer What about 380p? 280p.

[00:36:07]Answer B. 380p 28.

[00:36:34]Kelvin cycle.

[00:36:36]Kelvin cycle B C3 cycle fast carbon dioxide receptor carbon dioxide receptor RBarbon compound clearation addition of carbon dioxide 26 carbon unstable.

[00:37:15]So immediately reduction reduction ATP and NADPH reduction regeneration of the trios phosphate regeneration step reduction regeneration regeneration 180p reduction process reduction ATP regeneration total entp with the NDPS.

[00:38:26]We can say C3 cycle bundle cell C3 cycle way mell or bundle seat cell Hack C4 C4 carbon dioxide combined with PE in the presence of rubies.

[00:39:25]C3isco caroxil oxygen whole biosphere.

[00:39:48]So rubies most abundant enzyme in whole biosphere.

[00:40:08]PP caroxil PP caroxil compound C4 carbon dioxide compound C4 carbon dioxide phosphate compound compound three carbon compound carbon dioxide. First one.

[00:40:39]This one is bundle cell.

[00:41:02]Cell to junction bondic acid compound. Correct.

[00:41:26]acidic acid is unable to go to the bond cell.

[00:41:33]So oxal acidic acid malic acid and aspir and bundaroxide C3tomy around the vascular bundle.

[00:42:21]Correct. Okay. Next question number 18. In C3 plants, the fastable product of a photosynthesis during direct reaction is C3 plant. In C3 plants, the fastest stable product of a photosynthesis during direct reaction.

[00:42:45]C3 plants fastable product.

[00:43:08]C3 C4 C3 phosphoglyceric acid product C3 rice tomato sugar cane sum most important maze sugar cane sum C for cycle Hello.

[00:43:53]Next question. Respiration takes place in photo respiration bijam.

[00:44:12]Photo respiration takes place in photo respiration chloroplast mitochondria chloroplast perox mitochondria chloroplast cytoplasm mitochondria photo respiration photo respiration is a wasteful process neither sugar nor oxygen phosphoglycerin and phosphoglycolate are synthesized chloroplast instead of carbon dioxide.

[00:44:55]So it will bind with oxygen instead of carbon dioxide.

[00:45:04]Next question number 20. Bundle seat cells have these the following characters except whatever punam bond seed cells have these following characters except large in size large number of chloroplast threequal imperial to gas with intracellular space.

[00:45:42]Bundle sheet cellific.

[00:45:55]cellar.

[00:45:58]Correct.

[00:46:12]spine within no intracellular space.

[00:46:20]Intracellular space D will be the correct answer. Number during photo respiration.

[00:46:41]During photo respiration.

[00:46:50]BJ Punam respiration rubies bind.

[00:47:22]All of the correct next number photosynthesis takes place.

[00:47:28]Photosynthesis photosynthesis only in sunlight. Now only in yellow light. Now in the visible light obtained from any source. Now only in a very high intensity of light.

[00:47:47]Photosynthesis takes place in photosynthesis only in sunlight only in yellow light in the visible light obtained from any source only in very high intensity light.

[00:48:15]Obviously in the visible light from any source visible spectrum 400 to 700 natural artificial light for LED.

[00:48:45]Fluoroscent blog due to network issue.

[00:49:16]again.

[00:49:25]Thank you.
