💭Metabolism carbohydrates 1

#بالعربي كدا نقصد شنو بال Metabolism carbohydrates ؟؟
نقصد ال life cycle 🙂
بنقصد قصة حياة الكربوهيدرات مثلا من لما دخلت ال body لغاية ما اتكسرت وطلعت لينا energy 💜 (الي هم ال anabolsim و ال catabolsim)


#علشان نحصل على ال energy في النهاية يعني بندخل في كم pathway وكم steps 💜 وبتبدأ من:
💡digestion and absorption of CHO
(ال CHO اختصار لكربوهيدرات 💜)

💡formation of acetyle CoA

💡anabolsim and catabolsim

💡formation of ATP


العملية دي كلها اسمها ال Glycolysis : وهي العملية البتم فيها تناول الكربوهيدرات وتكسيرها في سلسلة من التفاعلات الكيميائية عن طريق انزيمات لوحدات صغيرة تتمثل في الجلكوز


💭عشان نفهم السلسلة من التفاعلات دي عبارة شنو عن. substrate 1 وبتلقى االانزيم الأول (البنسميهو ال key enzyme لانو هو الببدأ الشغل) بتتحول إلى. substrate 2 الي حتلقى enzyme 2 ويحولها لي substrate 3 الي حتلقى enzyme 3 وكدا القصة مكملة لغاية ما حنصل الsubstrate الاخيرة البنسميها ال.end product 💜

When glucose enters a cell, the enzyme hexokinase (or glucokinase, in the liver) rapidly adds a phosphate to convert it into glucose-6-phosphate. A kinase is a type of enzyme that adds a phosphate molecule to a substrate (in this case, glucose, but it can be true of other molecules also). This conversion step requires one ATP and essentially traps the glucose in the cell, preventing it from passing back through the plasma membrane, thus allowing glycolysis to proceed. It also functions to maintain a concentration gradient with higher glucose levels in the blood than in the tissues. By establishing this concentration gradient, the glucose in the blood will be able to flow from an area of high concentration (the blood) into an area of low concentration (the tissues) to be either used or stored. Hexokinase is found in nearly every tissue in the body. Glucokinase, on the other hand, is expressed in tissues that are active when blood glucose levels are high, such as the liver. Hexokinase has a higher affinity for glucose than glucokinase and therefore is able to convert glucose at a faster rate than glucokinase. This is important when levels of glucose are very low in the body, as it allows glucose to travel preferentially to those tissues that require it more.

Glycogenolysis: The breakdown or hydrolysis of glycogen in the liver (as well as kidneys, muscle and brain) into glucose which is released into the bloodstream.

Glycolysis: The oxidative breakdown or metabolism of glucose to produce energy

Glycogenesis: The conversion of excess glucose into glycogen as a cellular storage mechanism.

Gluconeogenesis: The reversal of glycogenolysis whereby glucose is synthesized within the body from non-carbohydrate substances, such as pyruvate, lactate, glycerol, and certain amino acids.

سلامعليكو ❤️
كيفكم يا دكاترة .. ان شاء الله كويسين!؟

معليش علي الانقطاع .. لنا عودة قريباً ان شاء الله.❤️
السلام عليكم يا دكاترة
بعتذر عن الغياب و التأخير بس ما كان عندي جوال ارسل منو فطولو بالكم شوية وان شاء الله ما يحصل الا خير 💙
