C. water
D. sugar
Answer

During cellular respiration, when pyruvic acid is created from glucose through glycolysis, the main additional byproducts are:

A. heat - A small amount of energy is released as heat during metabolic processes.
B. oxygen - This is not produced during glycolysis; oxygen is used later in the electron transport chain.
C. water - This is produced later in cellular respiration, but not directly from glycolysis.
D. sugar - This is consumed in the process, not produced.

Therefore, the best answer from the options provided is:

A. heat.

The correct answer is:

C. It is not electronegative, but oxygen is.

Oxygen is highly electronegative, meaning it has a strong tendency to attract electrons. This attraction causes a polar covalent bond to form with hydrogen atoms, which are less electronegative. This difference in electronegativity leads to the strong hydrogen bonds that form between oxygen and hydrogen, especially in water, which is crucial for many biochemical processes, including those in cellular respiration.
