Essay Phrases

Question 1

Importance of glucose

Answer 1

Glucose is the principal respiratory substrate, entering glycolysis to generate ATP, which provides the energy necessary for cellular processes such as active transport, biosynthesis and muscle contraction.

Question 2

Importance of ATP

Answer 2

ATP is crucial because it’s the cell’s go‑to energy source: breaking one of its phosphate bonds instantly releases the power needed for tasks like building new molecules, transporting substances in and out, moving muscles, and sending signals

Question 3

Importance of enzyme maintainance

Answer 3

Maintaining optimal enzyme action is essential because virtually all cellular processes depend on enzyme-controlled reactions. Enzymes have specific tertiary structures, and changes in temperature or pH can disrupt the hydrogen and ionic bonds that maintain this shape, leading to denaturation and loss of activity. If enzyme activity is not maintained, crucial processes such as cellular respiration, DNA replication, protein synthesis, and digestion cannot proceed efficiently.

Question 4

Importance of gene technology

Answer 4

Gene technology is important because it allows scientists to manipulate genetic material to improve medicine, agriculture, and our understanding of biological processes.

Question 5

Importance of immune response

Answer 5

The immune response is important because it protects the body against harmful pathogens, prevents disease, and provides long-term immunity through the formation of memory cells.

Question 6

water potential

Answer 6

Maintaining water potential is crucial because if it becomes too low, cells lose water and shrink (crenation), whereas if it becomes too high, water enters cells by osmosis, potentially causing them to swell and burst (lysis), both of which disrupt normal cellular functions.
