Without enzymes, the body couldn't perform essential chemical reactions quickly enough to sustain life. Enzymes also aid digestion and help in immune defence. Their absence would critically interrupt bodily functions and overall health.
If there were no enzymes in the human body, many essential biological processes would be negatively impacted. Enzymes act as biological catalysts, speeding up the chemical reactions that occur within cells, thereby allowing life-sustaining processes to occur at the rate necessary for life. If we didn't have enzymes, these reactions would happen too slowly to sustain life, or might not happen at all.
Enzymes are vital in breaking down food and converting it into usable energy. Without enzymes, our digestive system would not be able to efficiently break down nutrients, leading to malnutrition and energy deficiency. Moreover, enzymes are involved in the immune system's defence mechanisms. They assist in the destruction of foreign pathogens, thus protecting the body from infections.
Furthermore, each cell's enzyme demand changes according to its needs and role within the body. For instance, the enzymes necessary in stomach cells differ from those in skin, blood, or nerve cells reflecting the diverse functions enzymes perform in the human body.
Overall, without enzymes, the human body would be unable to function properly. They are essential for our survival, and their absence would dramatically alter the way our bodily systems operate.

B. have to pass through the G1, S, and G2 phases to prepare for division.
C. have to use binary fission to divide.
D. have to go through prophase, metaphase, anaphase, and telophase.
The right answer is C
"Binary fission" is the most common form of reproduction and cell division of prokaryotes. A cell, after replicating its genetic material, divides into 2, each part containing a copy of the genetic material and 2 new perfectly individualized cells are finally created, each having the ability to grow to the size of the parent cell of origin ... The chronology is as follows:
- replication of the bacterial chromosomal DNA and segregation into two nucleoids and cell growth phase;
- assembly of a protein ring of constriction;
- constriction of the ring associated with the wall synthesis until complete individualization of the 2 new cells.
carbon dioxide and uric acid
oxygen and urine
carbon dioxide and urine
The correct answer is option A
Plants performs both the functions photosynthesis and cellular respiration.The waste product of photosynthesis is oxygen that the plant releases in the environment.
Plants also performs cellular respiration and in the process of cellular respiration the waste product is carbon dioxide.
Hence, the waste products are carbon dioxide and oxygen.
Answer: D. cell
Explanation:
The cell theory suggested three proposed statements those were all living things are composed of cells, the cell is the smallest entity of life and all cells formed from the pre-existing cells. This discovery is attributed to Robert Hook, who first began the study of cells in his self constructed microscope. But two scientists named as Matthias Schleiden and Theodor Schwann were the contributors of this theory in 1839.
