Answer:

The enzyme is the pyruvate kinase

Explanation:

The designated enzyme can only grow in pyruvate or in ethanol. They are said to be in anaerobic conditions. If the end product of glycolysis is pyruvate and the enzyme that transforms phosphoenol pyruvate into pyruvate is called pyruvate kinase. In a reaction under anaerobic conditions, the pyruvate is transformed into ethanol. So if the pyruvate kinase enzyme is mutated, pyruvate cannot be transformed into ethanol and Saccharomyces cerevisiae could not survive in that medium.

Create a publication that will explain the evolution of taxonomy and the six kingdoms​
lakkis [162]

Answer:

Traditionally, some textbooks from the United States and Canada used a system of six kingdoms (Animalia, Plantae, Fungi, Protista, Archaea/Archaebacteria, and Bacteria/Eubacteria) while textbooks in countries like Great Britain, India, Greece, Brazil and other countries use five kingdoms only (Animalia, Plantae, Fungi, Protista and Monera).

Some recent classifications based on modern cladistics have explicitly abandoned the term "kingdom", noting that the traditional kingdoms are not monophyletic, i.e., do not consist of all the descendants of a common ancestor.

Which of the following is the simplest unit of a nucleic acid
Lyrx [107]
<span>Nucleotides are made of a pentode sugar, a phosphate and a nitrogen base. Nucleotides are the building blocks of nucleic acids DNA and RNA which serve as the cell's store house of genetic information. All nucleotides are composed of three parts: a five-carbon sugar, a phosphate and a nitrogen-rich structure called a nitrogenous base. The sugar can be ribose which is found in RNA, or deoxyribose which is found in DNA. The only difference between these two sugars is that deoxyribose has one fewer oxygen atom than ribose.</span>
