Asteady supply of is needed throughout the body in order for electrons to be accepted at the end of the electron transport chain.

Oxygen

The cells use oxygen molecules during oxidative phosphorylation. Oxidative phosphorylation is the final stage of cellular respiration which is made up of two closely connected components: 1) the electron transport chain and 2)chemiosmosis.

Oxygen sits at the end of this electron transport chain, where it accepts electrons and picks up protons to form water. If oxygen is not available to accept electrons, the electron transport chain will cease running, and ATP Adenosine triphosphate) will no longer be produced by chemiosmosis. Without enough ATP, cells can’t carry out the reactions they need to function, causing death.

answer; i do believe that the correct answer is; ///mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis;

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
