[00:00:07]Welcome to Heart of Education YouTube channel.

[00:00:22]again.

[00:00:29]Video number five.

[00:00:41]clearly.

[00:00:44]So immediately start Yes, the first question.

[00:01:11]The correct frequency of flow of electron in the light reactions reaction reaction. Light reaction. Dark reaction.

[00:01:22]Light reaction.

[00:01:26]Membrane. Dark reaction.

[00:01:29]reaction light and another one is noncleas.

[00:01:57]Cytochrome system A will be the correct answer here. Good evening.

[00:02:13]Clear system then sorry photos system one and feradoxin. Next question.

[00:02:34]Which of the following is a energy eling process?

[00:02:39]Energy process process mostly energy.

[00:02:44]Energy need two phosphoglycerate through two phospho pyate. Now fructose 2 fructose 6 phosphate. Now phosphenol pyroate to pyrovic acid. Now fructose 1 6 phosphate to phosphoglycerhide and dihydroxy acetone phosphate.

[00:03:06]Correct answer. Glycolysis.

[00:03:17]Glycolysis.

[00:03:33]Glucose. Glucose 6 phosphate. Glucose 6 phosphate. Fructose 6 phosphate fructose 16 fructose 16 B phosphate tap phosphoglycer dehyd dihydro acetone phosphate 13 B phosphoglycer acid three phosphogic acid two phosphoglyceric acid two phosphate and two pyrovic acid correct I hopey true pyrovic acid Cre which of Which type of phosphorilation occurs in mitochondria? Phosphoration mitochondria.

[00:04:12]Oxidative phosphorilation. Substrate level of phosphorilation. photosp.

[00:04:41]elect.

[00:05:01]phosphor.

[00:05:25]ATP, oxidative Substrate level D will be the correct answer.

[00:05:55]Ready? Next, the first stage in respiration.

[00:06:01]Respiration.

[00:06:05]What is the first stage of respiration?

[00:06:08]Respiration.

[00:06:17]break all living organism respiration.

[00:06:33]Suppose this one is the lungs and this is the elementary canal. Let's see this is the blood.

[00:06:54]break down respiration.

[00:07:24]Correct answerly.

[00:07:37]For example, Same age group.

[00:07:52]A group exam.

[00:08:18]I Foreign speech. Foreign speech.

[00:08:40]Foreign speech. Foreign speech. Foreign speech.

[00:09:03]74.

[00:09:09]Next live class vacuum nucleus periphery.

[00:09:24]Next class max% so that next pyroic acid dehydrogen is used in pyrovic dehydrogen pyrovate dehydrogen pyroate pyrovic The correct option to glucose glucose to pyroic acid.

[00:10:06]Now pyrovic acid to lactic acid pyrovic acid to acetyl oxidative means decaroxilation. Carbo carbon dioxide is removed and electron are transferred to form NADH oxidative decaroxilation.

[00:10:48]Correct. Next question.

[00:10:55]Which of the following is correct sequence in the crave cycle? Crave cycle. Correct sequence.

[00:11:01]Subraat. Sam Ma namaskar ma'am sir pron which of the following is the correct sequency in crave cycle cycle but acid cycle butilic acid cycle This cycle Acid, acid, second.

[00:12:16]Obviously Acitric acid. C4ic acid.

[00:12:48]nitric acid NADH plus NADH acidic acid.

[00:13:15]See, acidic acid. Acidic acidic acid malic acid malic plus release.

[00:14:15]Correct answer.

[00:14:34]Next question.

[00:14:41]What is respiratory question?

[00:15:05]Correct. Number one respiratory question. The ratio between carbon dioxide by oxygen.

[00:15:19]Volume of CO2 evolved by volume of O2.

[00:15:36]like carbohydrate or respiratory question.

[00:15:41]Carbohydrate or respiratory question.

[00:16:11]One protein fat less than one 0.8 0.1 carbohydrate one protein fat less than one respirator organic acid organic more than one 1.3 mic organic acid Acid.3 1.3 oxal seed four.

[00:17:04]Next question.

[00:17:09]Correct.

[00:17:12]Next.

[00:17:18]Partial pressure of car oxygen in atmospheric gear ali and deoxxyated blood and oxygenated blood and tissue.

[00:17:28]pressure.

[00:17:31]Answer pressure.

[00:17:53]lungs oxygenated bloodated blood. Suppose deoxxyinated blood pressure of oxygen. Second part of carbon dioxide.

[00:18:34]First, second, oxygenated blood, deoxxyated blood, tissue.

[00:19:01]Atmosphere 1590.3 deoxxygenated blood ready to Next. Oxygen binding to hemoglobin is directly proportional to carbon dioxide concentration. Directly proportional to carbon monoxide concentration. Inversely proportional to carbon dioxide concentration. Independent of carbon monoxide concentration. oxygen binding tomoglobin.

[00:20:08]Oxygen binding to hemoglobin is directly proportional to carbon dioxide.

[00:20:20]directly proportional to carbon monoxide. Now inversely proportional to carbon dioxide independent of carbon monoxide binding to hemoglobin.

[00:20:40]So answer inverse proportional to carbon dioxide concentration will be correct H2 CO3 carbon dioxide.

[00:21:14]carbon dioxide.

[00:21:18]Next carbon dioxide concentration binding of oxygen hemoglobin decreases.

[00:21:33]Next question.

[00:21:36]Select the incorrect statement from the following. Incorrect statement.

[00:21:42]Incorrect statement.

[00:22:03]Neural signal from neurotexistor can reduce duration of inspiration.

[00:22:09]Now the role of oxygen in regulation of a respiratory rhythm is quite significant. Kota incorrect. RBC contain very high concentration of enzyme carbonic anhydrates.

[00:22:23]Uh carbon dioxide carbon dioxide is carried by hemoglobin as carbon hemoglobin is 20 to 25%.

[00:22:42]and quantity of present in plasma. A B C D correctum center.

[00:23:11]So neotextor can reduce the duration of inspiration. Correct. Correct.

[00:23:17]Second option role of oxygen in the regulation of respiratory quite significant quite insificant oxygen respiratory incorrect carbon Carbon% carbon dioxide bicarbonate form oxygen oxyhemoglobin form. for direct sorry plasma. Third question, RBC contain a very high concentration of enzyme carbonic RBC and minute quantity of the same is present in a plasma.

[00:24:44]plasma also present in your plasma. This statement is correct. Mono carbonic nitrates is abundantly present in RBC.

[00:25:00]No doubt because it is important for the conversion of a carbonic acid. But yes, it is also correct that only extremely very small quantity of carbonic are also present in plasma.

[00:25:15]Heavy concentration present but concentration plasma.

[00:25:23]Next then catalogous ring in respiratory passage are present in respiratory passage.

[00:25:50]Rohit, Sonatan, Yika, Samoa, Soba, Cebu, Swaga.

[00:26:09]Respiratory, external nostalgings, nazal passage, nazings, lings, trachea, primary, secondary, tors, initial, terminal by catalogous incomplete catalogous ring.

[00:26:44]Correct.

[00:26:47]Next.

[00:27:00]Contract only.

[00:27:31]Relax, relax, relax, relax. Dear doctor, relax.

[00:27:53]restrict only 28 39 TBS apps tetray PB1 TBS PT1 ready.

[00:29:12]Ball carbon dioxide released from the body tissue into blood is present as Restrict restriction enducleus.

[00:30:01]too. Hello Hint hemophilus influction naming 70% RBC carbon dioxide maximum carbon dioxide A will be correct answer.

[00:31:20]Next.

[00:31:25]Mark the statement among the following and normal breathing.

[00:31:40]statement among the following with reference to normal breathing. Normal breathing correct incorrect inspiration got a passive process whereas expiration is active process.

[00:32:00]Inspiration is an active process where expiration is a passive process.

[00:32:08]Inspiration active process passive process correct B.

[00:32:27]Next, mark the true statement among the following with reference to normal breathing.

[00:32:49]In amphibian, heart hats.
