<span>Antibiotic resistance arises due to the evolution of the organisms they are designed to destroy. Subsequent generations of such organisms develop resistance to the antibiotic. Hospitals' overuse of antibiotics quickens the process, as does the administration of antibiotics to feedlot cattle, whose meat is consumed by people.</span>
Answer: False
Explanation:
Pathogens can be transmitted in many ways. It can spread by direct contact, indirect contact, or by vectors.
The mode of transmission can be skin contact, airborne particles, touching a surface, bodily fluids, touched by an infected person.
The mode of transmission can be vector that carries disease and helps in disease transmission.
So, the pathogens can be transmitted by direct contact, indirect contact or by vectors and by many more ways.
Answer:
<u><em>They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.</em></u>
Explanation:
Many mutations can lead to the formation of cancer. Cancer can be described as an abnormal type of cell division of the cells of the body. As cancer cells are the cells of the body dividing abnormally, the immune cells fail to fight them. These cells keep on dividing and also disturb the functioning of the neighbouring cells and tissues. They even take up most of the nutrients required by normal body cells hence, being very toxic for the normal cells.
Answer:
Hexokinase, Phosphofructokinase, Phosphoglycerate kinase and Pyruvate kinase
Explanation:
Coupled reactions are reactions that require energy by one process and is supplied by another; where the energy is transferred from one side of the reaction to the other.
In glycolysis, four (4) reactions undergo coupled reactions
1. Reaction one: which is the phosphorylation of glucose to glucose-6-phosphate coupled to the hydrolysis of ATP to ADP and Pi catalyzed by hexokinase.
2. Reaction three: The phosphorylation of fructose-6-phosphate to fructose-1-6-bisphosphate and the hydrolysis of ATP, catalyzed by phosphofructokinase
3. Reaction seven: Phosphoglycerate kinase catalyzes the conversion of Bisphoglycerate to 3-phoshoglycerate and the production of ATP from ADP
4. Reaction ten: Pyruvate kinase catalyzes the conversion of enol phosphate to the enolic form of pyruvate with the synthesis of ATP.
