4
36
Glycolysis yields 4 ATP molecules but consumes 2 ATP in early steps, resulting in a net gain of 2 ATP per glucose molecule.
Which process converts excess glucose into glycogen?
Gluconeogenesis
Glycogenesis
Glycogenolysis
Glycolysis
Glycogenesis is the pathway that synthesizes glycogen from glucose. Glycolysis breaks down glucose, gluconeogenesis forms glucose, and glycogenolysis degrades glycogen.
Which of the following foods has a low glycemic index?
Lentils
White bread
Glucose drink
Corn flakes
Lentils have a low glycemic index due to their high fiber and protein content, which slows glucose absorption. White bread, corn flakes, and glucose drinks raise blood sugar quickly.
Which food would likely cause the most rapid increase in blood glucose?
Glucose solution
Brown rice
Apple
Yogurt
A glucose solution contains simple sugar in free form and is absorbed very quickly, causing rapid blood glucose rise. Brown rice, apple, and yogurt have more complex or mixed nutrients slowing absorption.
What percentage of total daily calories is recommended to come from carbohydrates according to dietary guidelines?
45-65%
20-35%
10-20%
70-90%
Most dietary guidelines recommend that 45 - 65% of total daily calories come from carbohydrates to support energy needs and nutrient balance.
If someone consumes an 1800 kcal diet and 50% of calories come from carbohydrates, how many grams of carbohydrates should they eat?
275 g
225 g
200 g
250 g
Fifty percent of 1800 kcal equals 900 kcal from carbs. Since each gram of carbohydrate provides 4 kcal, 900 ÷ 4 = 225 grams.
Dietary fiber is classified as which type of carbohydrate?
Monosaccharide
Soluble lipid
Disaccharide
Indigestible polysaccharide
Dietary fiber is an indigestible polysaccharide that humans cannot break down, differing from mono- and disaccharides. It is not a lipid.
A meal with a high glycemic index is most likely to result in which immediate effect?
Increased ketone production
Rapid insulin spike
Slow digestion
Sustained low blood sugar
High-GI meals cause quick glucose absorption and a rapid insulin response. Slow digestion and ketone production are not typical outcomes of high-GI foods.
Which of the following meals is best for sustained energy release due to its carbohydrate composition?
Pancakes with syrup
Soda with glucose
Oatmeal with nuts and berries
White bagel with jam
Oatmeal with nuts and berries combines low-GI oats, fiber, and healthy fats for gradual glucose release. The other options rely on high-GI carbs for quick spikes.
Calculate the glycemic load for a food that has a glycemic index of 60 and contains 20 grams of available carbohydrate per serving.
6
20
60
12
Glycemic load is calculated as (GI à - grams of carb per serving) ÷ 100; thus 60 à - 20 ÷ 100 = 12.
An endurance athlete weighs 70 kg. Using a recommendation of 7 g of carbohydrate per kg for high-intensity training, how many grams of carbohydrates should they consume daily?
560 g
630 g
350 g
490 g
Multiplying 70 kg by 7 g/kg yields 490 grams of carbohydrate per day for high-intensity training.
What is the optimal carbohydrate-to-protein ratio recommended for post-exercise recovery?
3:1
1:1
2:1
1:3
A 3:1 carbohydrate-to-protein ratio (three parts carbs to one part protein) is widely recommended to maximize glycogen replenishment and support muscle repair.
Which of the following correctly compares carbohydrate recommendations for a sedentary adult versus an endurance athlete?
Sedentary: 1-2 g/kg, Athlete: 3-4 g/kg
Sedentary: 6-10 g/kg, Athlete: 3-5 g/kg
Sedentary: 3-5 g/kg, Athlete: 6-10 g/kg
Both: 5-7 g/kg
Sedentary individuals typically need about 3 - 5 g/kg, while endurance athletes require higher intake around 6 - 10 g/kg to meet energy demands.
A dietitian wants to lower the glycemic response of a high-GI meal. Which strategy is least effective?
Add vitamin C supplement
Add mixed vegetables
Add olive oil
Add chicken breast
Adding fiber, fat, and protein slows carbohydrate absorption and lowers glycemic response, while a vitamin C supplement has minimal impact on glucose absorption.

Cheat Sheet

  1. Understand the Three Main Types of Carbohydrates - Carbohydrates are grouped into sugars, starches, and fiber, each playing a unique role in your diet. Sugars give you quick bursts of energy, starches provide long-lasting fuel, and fiber keeps your digestive system happy. Get to know this trio to balance your plate and your energy levels! diabetes.org
  2. Differentiate Between Simple and Complex Carbohydrates - Simple carbs, found in candy and soda, break down quickly and can send your blood sugar soaring. Complex carbs in whole grains and legumes release energy slowly, helping you feel fuller longer. Spotting the difference empowers you to choose smarter snacks! healthline.com
  3. Recognize the Role of Carbohydrates in Energy Metabolism - Think of carbs as your body's favorite fuel: they're converted into glucose, which powers every cell. Without enough carbs, your energy dips and your muscles won't perform at their best. Mastering this concept helps you plan meals that keep you energized all day. my.clevelandclinic.org
  4. Learn About the Glycemic Index (GI) - The GI tells you how fast a food raises blood sugar, with high-GI snacks causing quick spikes and low-GI options offering steady energy. Choosing low-GI foods can help you avoid sugar crashes and keep focus in class. It's like having a cheat sheet for smarter eating! healthline.com
  5. Understand Daily Carbohydrate Intake Recommendations - Carbohydrate needs differ by age, activity level, and health goals, but generally should make up 45 - 65% of your daily calories. Athletes or active students might aim higher, while a more sedentary routine calls for a moderate approach. Balancing your plate ensures you get enough energy without overdoing it! my.clevelandclinic.org
  6. Identify Healthy Sources of Carbohydrates - Whole grains, fruits, vegetables, and legumes aren't just tasty - they pack vitamins, minerals, and fiber to fuel your brain and body. Swapping out refined foods for these powerhouses boosts your nutrient intake. Snack smart and watch your grades (and energy) soar! heart.org
  7. Limit Intake of Added Sugars - Too many sweets and sugary drinks can lead to energy crashes, weight gain, and long-term health issues. Aim to read labels and choose natural sweetness from fruits instead of hidden sugars. Your body and brain will thank you with better focus and stamina! heart.org
  8. Incorporate Fiber for Digestive Health - Fiber isn't just filler - it feeds the good bacteria in your gut, aids digestion, and helps control blood sugar. Foods like beans, oats, and broccoli are your new best friends for staying regular. A fiber-rich diet is a happy-gut diet! diabetes.org
  9. Be Aware of Refined vs. Whole Grains - Refined grains have the bran and germ removed, stripping away fiber and nutrients, while whole grains retain all the good stuff. Choosing whole-grain bread, pasta, and rice helps you absorb more vitamins and minerals. Say goodbye to empty calories and hello to lasting energy! heart.org
  10. Apply Carbohydrate Knowledge to Meal Planning - Balance your plate by pairing complex carbs with lean proteins and healthy fats for a combo that fuels study sessions and workouts.
