The first stage of cellular respiration, glycolysis, results in two pyruvate molecules. those pyruvate molecules are then used in what stage of cellular respiration?

a. active transport
b. phosphorylation
c. the electron transport chain
d. the krebs cycle

The correct answer would be d. the Krebs cycle.

Explanation:

Cellular respiration is a bunch of metabolic processes and reactions that take place in the cells to convert chemical energy from glucose into adenosine triphosphate and then release waste products. Cellular respiration can be divided into three cycles - glycolysis, the Krebs cycle, and the ETS cycle.

In glycolysis glucose converted into two molecules of pyruvate. Oxidative carboxylation of the pyruvate molecule produces acetyl CoA. Acetyl CoA enters into the Krebs cycle which utilizes them and produces ATP.

Thus, the correct option is D. the Krebs cycle.

i also need this answer for on a project, does anyone know the answer? ?

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
