Is oxygen nessesary to produce atp in your cells

 No. 

Glycolysis doesn't need oxygen to produce ATP. 
Aerobic respiration (i.e. through electron transport chain in mitochondria) needs oxygen. 

Duke: the products of glycolysis CAN go into the oxidative cycle, or if there is no oxygen they will go into the lactic acid cycle, which creates lactic acid as a byproduct. So yes, glycolysis does produce ATP without oxygen, and yes it is far too inefficient to allow a human to live without O2, but you can get simple organisms like yeast to survive this way, for example.

Ithink the answer is a or d i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
