Item 8

Which of the following statements is true concerning how energy drinks work?

Multiple Choice

• Energy drinks contain vast amounts of carbohydrates and proteins that enter into cellular respiration pathways, directly providing ATP energy.

• Energy drinks contain numerous vitamins and minerals which are known to directly act as stimulants.

• Energy drinks contain vitamins which are known to interact with cellular respiration pathways, helping provide energy.

• All energy drinks contain caffeine, as it is a known stimulant that increases energy levels.

• It is the amount of food additives in energy drinks that provides the energy felt.

The largest number of ATP molecules is produced in which phase of cellular respiration?

Multiple Choice

• glycolysis

• preparation reaction

• citric acid cycle

• electron transport chain

Answer 1

Energy drinks contains almost the same amount of caffine (80mg) as a cup of coffee. Caffine blocks the action of adenosine present in brain and responsible for sleep. By blocking adenosine caffine works as stimulant and activate the neurons in the brains.

So option 4 (all energy drinks contains caffine a known stimulant) is correct answer

From oxidation of 1 glucose molecule, 2 molecules of ATP is produced by glycolysis and 2 molecules of ATP are produced by Krebs cycle. Rest of the 28 molecules of ATP are produced by electron transport chain.

So electron transport chain is correct answer.
