Answer:
2 molecules of ATP
Explanation:
Glycolysis is the anaerobic process (no oxygen required) used in the breakdown of glucose to extract energy. It occurs in the cytoplasm of both prokaryotic and eukaryotic cells. It is the first step of cellular respiration.
Glycolysis is subdivided into two phases: the first phase uses energy (ATP), while the second phase produces it together with pyruvate and NADH.
Two molecules of ATP are required for the first stage of glycolysis, while 4 ATP molecules and 2 NADH molecules are formed in the second stage.
Answer:
There are no options in this question but generally a sample of DNA can be increased;
By using Polymerase Chain Reaction (PCR) technique.
Explanation:
This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.
In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.
The two main types of fermentation are alcoholic fermentation and lactic acid fermentation. In an alcoholic fermentation, the main product of this process is ethyl alcohol. Lactic acid on the other hand has lactic acid as its main product. When muscle cells run out of oxygen, lactic acid fermentation would commonly take place.<span> </span>
