Question 4(Multiple Choice Worth 5 points) (04.06 HC)

The masses of all the substances either used up or formed during cellular respiration are shown below: A = 360 grams, B = 216 grams, C = 384 grams, D = 528 grams Which of the following statements supports the conclusion that cellular respiration follows the law of conservation?

The total mass of A and B, which are glucose and oxygen, is less than the total mass of C and D, which are water and carbon dioxide.
The total mass of C and D, which are glucose and oxygen, is greater than the total mass of A and B, which are water and carbon dioxide.
The total mass of A and C, which are glucose and water, is equal to the total mass of B and D, which are oxygen and carbon dioxide.
The total mass of A and C, which are glucose and oxygen, is equal to the total mass of B and D, which are water and carbon dioxide.

Answer 1

The total mass of A and C which are glucose and oxygen, is equal to the total mass of B and D, which are water and Carbon dioxide.

Answer 2

The total mass of A and C which are glucose and oxygen, is equal to the total mass of B and D, which are water and Carbon dioxide.

the law of conservation states that no energy or matter should be lost during a reaction therefore total masses should be equal so you're looking to 2 numbers that equal each other when added and the only 2 are A and C equal B and D

In respiration we know that the waste products are water vapor (H2O) and carbon dioxide.
Which makes the last statement correct.
