What role do proteins play in cellular processes?
✔✔ Proteins serve as enzymes, structural components, and signaling molecules, playing a key
role in cellular functions.
How does the structure of a phospholipid contribute to the formation of cell membranes?
✔✔ Phospholipids have hydrophilic heads and hydrophobic tails, forming a bilayer that creates a
selective barrier for the cell.
Why is the process of homeostasis critical for survival?
✔✔ Homeostasis maintains a stable internal environment, allowing organisms to function
properly despite external changes.
What is the primary purpose of cellular respiration?
✔✔ To convert the energy stored in glucose into ATP, which cells use to perform various
functions.

, How does the surface area-to-volume ratio limit the size of a cell?
✔✔ As a cell grows, its surface area increases at a slower rate than its volume, limiting the
efficiency of material exchange across the cell membrane.
What is the significance of hydrogen bonds in the structure of water?
✔✔ Hydrogen bonds give water its unique properties, such as high cohesion, adhesion, and the
ability to moderate temperature.
Why are macromolecules essential to living organisms?
✔✔ Macromolecules, such as carbohydrates, lipids, proteins, and nucleic acids, are the building
blocks of cells and are essential for growth, energy, and cell function.
How do living organisms exhibit organization from the cellular level to the organismal level?
✔✔ Organisms are made up of cells, which group into tissues, organs, organ systems, and finally
form a complete organism.
What is the significance of cellular differentiation in multicellular organisms?
✔✔ Cellular differentiation allows cells to develop specific functions, enabling the formation of
complex tissues and organs.
