It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. The pathway that produces the most NADH and the least ATP is the KREBS CYCLE. Hope this answers your question. Have a great day ahead!
B. Light energy and heat energy!
This is because the thermal energy which is the heat. As you know fire heats up and burns, a lit candle would do just the seem. Also the fire is bright enough to light up an area!
Enzymes that eventually break down the surface of bacteria are found in saliva, mucus, and tears, which act as chemical barriers against infection.
Enzymes found in saliva, mucous, as well as tears that degrade bacterial surfaces serve as chemical barriers preventing infection. The stomach's acid as well as the acid in sweat both destroy cellular pathogens, and even the semen contains antibacterial proteins.
There is no chemical and physical barrier offered by macrophages. Instead of acting as a barrier, macrophages target pathogens once they have already entered the body. Physical barriers include mucus as well as stratified squamous epithelium, whereas chemical barriers include saliva and urine.
Therefore, Enzymes that eventually break down the surface of bacteria are found in saliva, mucus, and tears, which act as chemical barriers against infection.
