The final acceptor of electrons in the electron transport chain is molecular oxygen. Electron transport chains are used for extracting energy via redox reactions from sunlight in photosynthesis or, such as in the case of the oxidation of sugars, cellular respiration.
On their website, the American Diabetes Association directs diabetics to eat between 45-60 grams of carbohydrates at each meal. Assuming a person eats three meals a day, this advice works out to telling diabetics to eat a minimum of 135 grams to a maximum of 180 grams of carbohydrates per day.
The recommended intake is a minimum of 130 grams/day, or 45 - 65 percent of daily calories for adults, independent of age or activity level. This is the minimum needed for your brain to function. Athletes are recommended to consume 6 - 10 grams for every kilogram of body weight per day.For example, a typical man weighing 70 kilograms needs 420 grams of carbs per day to fuel his activity.If you are on a low-calorie diet (less than 2000 calories per day), it may be difficult to achieve the 6 grams per day.ince there are four calories per one gram of carbohydrate, you would need to be consuming 250-300 grams of carbohydrates per day. The digestibility of the carbohydrates you consume (fiber content) plays a role in the physiological energy available.
