Recall how many Calories are in 1 kcal
. Compare 41 Calories
to 410 kcal
(1 kcal=1,000 calories
).(1 point)
Responses

41 Calories
is greater than 410 kcal
41 Calories is greater than 410 kcal

41 Calories
is less than 410 kcal
41 Calories is less than 410 kcal

41 Calories
is equal to 410 kcal
41 Calories is equal to 410 kcal

It is not possible to compare these two values.

41 Calories (which is equivalent to 41 kcal since 1 Calorie = 1 kcal) is less than 410 kcal. Therefore, the correct response is:

41 Calories is less than 410 kcal.

You want to build a model of aerobic cellular respiration. What should it show about the relationship between oxygen and energy production?(1 point)
Responses

Oxygen combines with glucose to directly form ATP and water.
Oxygen combines with glucose to directly form ATP and water.

Oxygen is used to split glucose molecules, releasing energy.
Oxygen is used to split glucose molecules, releasing energy.

Oxygen is not necessary during cellular respiration, just during photosynthesis.
Oxygen is not necessary during cellular respiration, just during photosynthesis.

Oxygen is a waste product that is released during energy production.

In aerobic cellular respiration, oxygen plays a crucial role in the process. The correct response is:

Oxygen combines with glucose to directly form ATP and water.

This illustrates that oxygen is essential for the extraction of energy from glucose, leading to the production of ATP and water as byproducts in the process of cellular respiration.

During cellular respiration, energy is released. What would a model need to show to accurately demonstrate that matter is rearranged, and energy is conserved in the process?(1 point)
Responses

Energy being created as glucose is consumed and oxygen is used.
Energy being created as glucose is consumed and oxygen is used.

Oxygen molecules combining with carbon atoms to create new substances without changing the mass.
Oxygen molecules combining with carbon atoms to create new substances without changing the mass.

Visuals showing that more energy is produced than consumed when water and carbon dioxide are combined to highlight the conservation of matter.
Visuals showing that more energy is produced than consumed when water and carbon dioxide are combined to highlight the conservation of matter.

Glucose and oxygen breaking into carbon dioxide and water, showing that the mass remains the same and energy is released.

To accurately demonstrate that matter is rearranged and energy is conserved during cellular respiration, a model would need to show:

Glucose and oxygen breaking into carbon dioxide and water, showing that the mass remains the same and energy is released.

This response highlights the conversion of reactants (glucose and oxygen) into products (carbon dioxide and water), while emphasizing the conservation of mass and the release of energy in the process.
