In muscle cells, fermentation produces _____.
algol13

Answer:

The correct answer is E. Lactate and NAD+

Explanation:

Fermentation occurs in anaerobic condition and in humans, most of the energy is provided by aerobic respiration but when the body needs a lot of energy in a very quick time like in sprinting then muscles use lactic acid fermentation to gain energy.

After the consumption of all stored ATP during intense work, our body starts lactic acid fermentation to gain ATP. In lactic acid fermentation, the pyruvate molecule that was produced during glycolysis is converted into lactate molecule. In this process, NADH is oxidized to NAD+.  

Therefore in lactic acid fermentation lactate and NAD+ are produced. So the correct answer is E.

Ipatiy [6.2K]

Answer:

Saturated fats/ solid fats

Explanation:

Vegetable oils amongst other unsaturated oils are liquids at room temperature while saturated oils are solids or spreadable at room temperature.

Industrially, vegetable oils are hydrogenated; hydrogenation is the process of adding hydrogen to an unsaturated compound to make it saturated. This then makes these hydrogenated vegetable oil, saturated which makes them solids as earlier stated, they are also called cis - fatty acids.

Trans - fatty acids as well are also unsaturated oils which are hydrogenated industrially to give saturated fatty acids which are called artificial tran-fats. They are found in most commonly found in baked and fried goods.
