What are water and carbon dioxide in the cellular respiration reaction?

they are reactants because they are present before the reaction.
they are reactants because they are present after the reaction.
they are products because they are present before the reaction.
they are products because they are present after the reaction.

They are products because they are present after the reaction.

Reactants are present before the reactions, products are after the reaction. so you can rule out the 2 and 3 option. The water is released after the electron transport chain and the carbon dioxide is produced after the Krebs cycle. So they are products so the answer is the fourth one.

Answer   D. They are products because they are present after the reaction.

Explanation:  Took the test got a 100%

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
