Preferred access point for a superficial venous blood draw is the right subclavian vein external jugular vein median cubital vein axillary vein brachiocephalic vein

         The correct option is MEDIAN CUBITAL VEIN.

Reason:

Right sub clavian vein:

                   It receives blood from right lymphatic duct and also empties its lymph from the body inside it.  

External jugular vein:

                   It drains blood from the head, brain, face and neck.

Median cubital vein:

                   It is superficial vein of upper limbs.  It receives blood from basilic and cephalic vein  

Axillary vein:

                   It carry deoxygenated blood from thorax, armpits, and upper limbs toward the heart.

Brachiocephalic vein:

It carries deoxygenated blood from the rib cage to superior vena cava of heart.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

hey, what do you need . just post the question and i may be able to you : )
