What is the primary molecule produced by cells when nutrients are oxidized to perform cellular work?

• Glucose

• ATP

• DNA

• Oxygen

How is the amount of energy in nutrients chemically determined?

• By the weight of the nutrients

• By the volume of the nutrients

• By the calories they contain

• By the color of the nutrients

What instrument do food chemists use to measure the ability of food to generate heat?

• Thermometer

• Barometer

• Calorimeter

• Spectrophotometer

What is a calorie defined as?

• The amount of energy required to raise the temperature of 1 liter of water by 1°C at 1 ATM

• The amount of energy required to raise the temperature of 1 gram of water by 1°C at 1 ATM

• The amount of energy required to raise the temperature of 100 grams of water by 1°C at 1 ATM

• The amount of energy required to raise the temperature of 10 grams of water by 10°C at 1 ATM

What is the equivalent of 1 small calorie in joules?

• 4.2 joules

• 1 joule

• 2.5 joules

• Nutrients that the body can produce in large quantities

• Nutrients not required for normal human body function

• Nutrients required for normal human body function, must be taken in with diet

• Nutrients that are only found in supplements

Why can't essential nutrients be made by the body?

• Because the body can make them in sufficient quantities

• Because they are not necessary for health

• Because they can be made by body cells but not fast enough to meet changing demands

• Because they are harmful to the body

What is the correct order of nutrient utilization by the body?

• LIPIDS > CARBO > PRO

• PRO > CARBO > LIPIDS

• CARBO > PRO > LIPIDS

• CARBO > LIPIDS > PRO

Which of the following is considered a major nutrient?

• Vitamins

• Water

• Carbohydrates

• Minerals
