Where in aerobic respiration is the largest amount of energy produced?

A)

At the beginning of the cycle, when glucose is oxidized to pyruvate.

B)

At the end of the electron transport chain, when oxygen is reduced.

C)

At the end of the electron-transport chain, when oxygen is oxidized.

D)

At the beginning of the electron transport chain, when oxygen is oxidized.

What happens to the glucose molecule during the process of cellular respiration? (5 points) select one: a. it gets broken down. b. it forms oxygen. c. it builds muscles. d. it uses up energy.

Achemist who studies water samples did a demonstration of how to test for lead in water. she added a clear solution of potassium iodide to a clear solution of lead nitrate. then a yellow swirling solid formed in the liquid. what is most likely true about the yellow solid?

The allotropes of carbon include a variety of structures that include three-dimensional tetrahedral lattices, planes of hexagonal rings, cylindrical tubes of hexagonal rings, and spheres of five- and six-membered rings. similar shapes of network covalent atomic solids are possible with carbon nitride, boron, and pure silicon (e.g., silicene is a graphene-like allotrope of pure silicon). in contrast, silicates exist as either highly ordered or amorphous (more random) three-dimensional lattices. what could explain why there are there no naturally occurring sheets, stacked sheets, cylindrical tubes, or spheres of network covalent atomic solids composed of silicon and oxygen (sio2)? would pure silicate structures make good lubricants or good electrical conductors?
