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.
Your minimum carbohydrate needs are 130 grams per day, which is the recommended dietary allowance, or RDA, for carbohydrates, according to the Institute of Medicine. If youâre pregnant or nursing, your carb RDA is 175 grams or 210 grams per day, respectively. Most athletes require additional carbohydrates.
