Answer:
A change in pH will cause many cellular processes to be disrupted because they affect the biomolecules (protein and nucleic acid) responsible for these processes.
Explanation:
pH refers to the degree of acidity or alkalinity. In a cell, the structures and processes that occur in them are impossible without the biomolecules, which are carbohydrate, protein, lipids and protein.
However, unfavorable conditions like a change in pH can cause the structure of some of these biomolecules to be affected. Proteins are made up of amino acids, which gives them their shape that is peculiar to their functioning. Also, nucleic acids such as DNA are composed of nucleotides responsible for their functioning.
A change in pH will cause the bonds of the protein to be disrupted, hence altering its shape and ultimately its functioning. Likewise, the hydrogen bonds in the DNA will be broken in the presence of a high pH causing the DNA to be dysfunctional.
When these biomolecules are affected, the vital functions that they perform in a cell, which is key to the cell's survival are disrupted) are likewise affected. Therefore, the cell is affected negatively.
C) Lactic acid and energy
This is the reason we feel a burning sensation during strenuous exercise.
Answer:
B carbon dioxide
Explanation:
the process uses oxygen and produces carbon dioxide as a waste product.
Answer:
The LapF gene encodes one of the largest proteins from Pseudomonas putida, it is required for the bacterial colonization on the solid surfaces; while naphthalene dioxygenase is an enzyme required for the process of aerobic degradation of naphthalene.
Explanation:
LapF is a gene of Pseudomonas putida that is critical during the process of plant root colonization. Mutations in this gene have shown to reduce the ability to colonize plant tissues. On the other hand, the naphthalene dioxygenase gene is also encoded by the genome of Pseudomonas strains. The naphthalene dioxygenase protein catalyzes the hydroxylation of different substrates, however, this enzyme is widely known for acting during the degradation of naphthalene, an organic chemical compound that is toxic in humans.
