What is the primary energy-transferring molecule in cells? When broken (hydrolyzed), the high-energy phosphate bonds in the ATP molecule release the energy used to do cellular work.
What is the primary energy-transferring compound of the body?
A&P Quiz 1 CH. 1-3
| Question | Answer |
|---|---|

| What are the 3 main parts of a human cell? | Plasma membrane, cytoplasm, and nucleus. |
| In what order do elements interact in a homeostatic control system? | The receptor, the control center and the effector. |
What is the most abundant and most important molecule for transferring information?
Polymers of nucleotides; largest is DNA. Constitutes our genes, gives instructions for synthesizing all of the body’s proteins, and transfers hereditary information from cell to cell when cells divide and from generation to generation when organisms reproduce.
What is the body’s most important energy transfer molecule?
Adenosine Triphosphate
What compound is the most abundant in a cell?
water
Is the human body made of cells?
The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells have many parts, each with a different function.
Are cells made of DNA?
Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
How was the cell discovered?
The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope.
