The major end products of the electron transport chain are a. glucose and amino acids b. dietary fiber and ammonia c. water, carbon dioxide and ATP d. carbon, nitrogen and hydrogen

The major end products of electron transport chain are water carbon dioxide and ATP.

So option C is correct one.

Explanation:

The process of forming ATP from the electron transport chain is known as oxidative phosphorylation. Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed. Three ATPs are formed from each NADH + H+, and two ATPs are formed for each FADH2 in eukaryotes.

Electron carriers are reduced during glycolysis and the citric acid cycle to NADH + H+ and FADH2. These carriers then donate electrons and protons to the electron carrier proteins of the electron transport chain. Together with oxygen, electrons and protons form molecules of water.

1.the evidene of the reaction

2.yes

3.yes

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
