Answer:
A. anaerobic respiration in muscle cells, forming lactic acid
Explanation:
Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.
The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.
Answer: El smog fotoquímico se forma cuando los fotones de la luz solar chocan con moléculas de diferentes tipos de agentes contaminantes en la atmósfera. Los fotones hacen que se produzcan reacciones químicas. Las moléculas de contaminación se convierten en otros productos químicos nocivos, como ya venimos en el laboratorio.
Explanation:
Alcoholic fermentation and indeed most forms of fermentation are low-energy producing. The waste products are often medium-sized hydrocarbons/alcohols that, when fully oxidized to carbon dioxide provide more energy.
Cells ferment sugars to lactic acid B. During training. This is why your muscles are sore and sore during exercise. Essentially, building this lactic acid causes your muscles to scream for oxygen and use a simplified fermentation process to meet their energy needs, which is not efficient at all.
Yes, animals will ferment for a short time if they are not supplied with enough oxygen. Humans perform lactic acid fermentation when the body urgently needs a lot of energy. If you sprint as fast as you can, your cells only have a few seconds of ATP stored. When stored ATP is depleted, muscles begin to produce ATP through lactic acid fermentation.
