Energy and respiration part 2

Multiple Choice

Which one is absent in a molecule of ATP?

• deoxyribose

• pentose

• adenine

• phosphate

Multiple Choice

ATP is known as the universal currency of energy. ATP is a phosphorylated nucleotide which is known as a ‘high energy’ molecule. It is made of an organic base, adenine, a 5 carbon sugar named .... and three phosphate groups.

• Ribose

• Water

• Hydrolysis

• Active-Transport

Multiple Choice

The removal of the outer phosphate group by the process of .... releases energy.

• Ribose

• Water

• Hydrolysis

• Active-Transport

Multiple Choice

Which nutrient provides the most energy?

• Proteins
• Fats
• Carbohydrates
• Vitamins

Multiple Choice

What is NOT true about percentage daily value (%DV)?

• It allows you to compare 2 foods and find out which is healthier

• It allows you to find out if a nutrient is medium low or high

• You can use it to calculate how much gram (g) fat or protein is in more than one serving of a food

• It is for an entire day, not just for one meal

Multiple Choice

How many calories would you consume if you ate the entire product? 

• 50
• 200
• 990
• 110

Multiple Choice

You consume 2 servings of ice cream, how many calories are you consuming?

• 150

• 275

• 300

• 350

Role of hydrogen atoms 

• Hydrogen carrier molecules called NAD and FAD pick them up (become reduced) and transfer them to the inner mitochondrial membrane. 

• Reduced NAD and FAD release the hydrogen atoms which split into protons and electrons. 

Multiple Choice

Which molecule isn't a high energy hydrogen carrier?

• FADH₂
• NADH
• oxygen

Multiple Choice

What role do NADH and FADH2 (produced during Glycolysis and Kreb's Cycle) play in cellular respiration

• they are energy carriers (hydrogen)that use that energy to produce massive amounts of ATP

• They are waste products and are pushed out of the cell

• They are necessary for long-term energy storage

• They don't play any role in cellular respiration
