Answer:
about 5 billion years ago
Explanation:
Our solar system formed about 5 billion years a go from a dense cloud of interstellar gas and dust.
Answer: Yes.
Explanation:
Fermentation is a general term denoting anaerobic degradation of glucose or other organic nutrients in various products to obtain energy in the form of ATP. Fermentation occurs when, after glycolysis, the Krebs cycle is not performed, because the organism does not have it or because this pathway is blocked, such as during hypoxia (lack of oxygen). Fermentation is a process used by bacteria to obtain energy, does not use oxygen and occurs in the cytoplasm of cells, ie an intracellular process, and each step is catalyzed with the help of different enzymes.
Some industries use this process in the production of some products, known to all of us, such as:
1. yogurt is produced by the famous lactic fermentation, where bacteria called lactobacilli to produce lactic acid.
2. bread and beer are produced by alcoholic fermentation, where the fermentation is carried out by fungi (facultative anaerobic), which ultimately produce alcohol;
3. vinegar to that produced by acetic fermentation, which consists of a chemical reaction, where partial oxidation of ethyl alcohol occurs, obtaining acetic acid.
The answer is Glycogenolysis
When we are hungry or skipped a meal our glucagon, <span>an hormones</span> that regulates blood-sugar levels, is released to avoid glucose levels in the blood to decrease to a risky value.
Glucagon makes the liver, but also the muscle, to breakdown accumulated glucose called glycogen into glucose to increase blood-sugar levels. This process is called Glycogenolysis and can also be stimulated by an increase in epinephrine during fight-or-flight responses.
In the DNA, that is why they are called the building blocks of life.
