Based on the above figures, do you think the 120 grams of glucose metabolized by the brain daily can sufficiently fuel all of the brain's daily metabolic activities? Support your answer with calculations.
Clue: You need to find out the total (estimated) number of brain cells. You also need to use your basic knowledge of mole/mass/number of particles calculations in answering the problem.
Leave your briefly explained answer as comment below. Do not forget to include your name. Submit your calculations separately using 1 short-sized bond paper...
yes?because the brain metabolizes approximately 120g of glucose daily and hypoglycemia can reduce the brains energy supply,causing dizziness and loss of consciousness.During the time of fasting ,even though the body is continuously using glucose for the production of heat and energy,the amount of glucose present in the blood remains fairly constant,usually in the range of 70 to 100mg per 100ml

yes, 120 grams of glucose can sufficiently fuel all of the brain's metabolic activities. Glucose molecules enter the cell by hundreds of thousands. They are processed simultaneously to generate millions of ATP molecules every second.

It starts with a single cell. The first cell splits to become two and the two becoe four and so on. After just forty-seven doubling, you have ten thousand trillion cells in your body and are ready to spring forth as a human being.Your cells are a country of ten thousand trillion citizens, each devoted in some intensively specific way to your overall well-being."Cells and microorganisms have an impressive capacity for adjusting their intracellular machinery in response to changes in their environment, food availability, and developmental state. Add to this an amazing ability to correct internal errors--battling the effects of such mistakes as Permanent structural alterations in DNA, consisting of either substitutions, insertions or deletions of nucleotide bases.mutations or misfolded Organic compounds made of amino acids arranged in a linear chain, joined together by peptide bonds between the carboxyl and amino groups of the adjacent amino acid residues.proteins--and we arrive at a major issue of contemporary cell biology.

120g glucose x 36mol of ATP/g glucose=432mol of glucose.
therefore, 120g of glucose will not suffice the brain's daily ATP requirement.Amber Ann I.Aganan FS-3A

ReplyDeleteNO, the 120 grams of glucose metabolized by the brain daily can not sufficiently fuel all of the brain's daily metabolic activities. The energy consumption is higher compared to energy production.
ReplyDeleteENERGY CONSUMPTION
(total ATP consumption per day)
= seconds per day*10M*100B
= 8.64x10^22
ENERGY PRODUCTION
= 1.4525406x10^25
Thats the reason why we must have a daily intake of carbs and it should always be included in our daily diet since everyday we use energy both by our body and brain's daily metabolic activities. We must supply an additional glucose to produce more ATP (energy) which is/are needed by our brain in its daily metabolic activities.

yes,it will be metabolized because glucose is needed to perform the activities its a simple sugar that the body needs most it is needed for brain development its also a carbohydrate that serves as fuel daily.

No, 120 grams of glucose metabolized by the brain daily cannot sufficiently fuel all the of the brain's daily metabolic activities because the energy consumption is greater than energy production..

yes, it can supply because the brain consumption is 432 x 10 rise to 20 and the energy production is 4.00932 x 10 rise to 23.

NO, because the energy prod. is 40% of the enrgy of the glucose to ATP, the 60% is released. the estimated # of brain cells is 1,400 grms. the tota is 168,000. aside from that the total ATP is 36 so i think i'am correct in my estimated regarding the question but i can not explain to the word and also to the right calculation.

If my calculations are correct the energy released by 120g of glucose during metabolism is more than ample to sustain the brain with enough energy for it to function at peak efficiency.

from: http://hypertextbook.com/facts/2001/JacquelineLing.shtml
In some research the the brain (though it only weighs 2% of the body) consumes 20% of the overall energy produced by the body or 23.3W from the overall 116W produced during metabolism.
Based on a 2400 calorie diet (Adapted from Yang)
2400 "food calorie" = 2400 kcal
2400 kcal / 24 hr = 100 kcal/hr = 27.8 cal/sec = 116.38 J/s = 116 W
20% x 116 W = 23.3 W

yes,the 120grams of glucose will suffice the brain's daily ATP requirement because the ATP consumption is 8.64x10 to the twenty-two power and the ATP production is 1.45x10 to the twenty-fifth power so the energy production is higher than energy consumption. Amber Ann I. Aganan BSFSIM-3A.

ReplyDeleteYes! 120 grams of glucose is enough to fuel the brain in its daily metabolic activities. Because according to my computation, there were 10 billion of brain cells present in a human brain which consume the 120grams production of glucose. And i think it is the normal computation of a human to do his/her task, because, if that energy production and comsumption is not enough I think all people wouldn't do their jobs/tasks correctly.
