What is glycogen?

Back

Glycogen is a polysaccharide that serves as a form of energy storage in animals, composed of long chains of glucose molecules.

Front

What is a hypertonic solution?

Back

A hypertonic solution is one where the concentration of solute is greater outside the cell than inside, causing water to leave the cell.

Front

What effect does salt have on the freezing point of water?

Back

Salt lowers the freezing point of water, meaning that water with salt will freeze at a lower temperature than pure water.

Front

What should you do first if you break a glass beaker in a lab?

Back

You should inform your teacher immediately to ensure proper safety procedures are followed.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are essential for protein synthesis, allowing cells to produce proteins necessary for various functions.

Front

Define polysaccharide.

Back

A polysaccharide is a carbohydrate molecule composed of long chains of monosaccharide units, such as glucose.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is the function of the nucleus in a cell?

Back

The nucleus houses the cell's DNA, which contains the genetic information necessary for protein synthesis and cell function.

Front

What is the difference between a hypertonic and hypotonic solution?

Back

A hypertonic solution has a higher concentration of solute compared to the cell, while a hypotonic solution has a lower concentration of solute.

Front

What is the importance of protein synthesis in cells?

Back

Protein synthesis is crucial for cell growth, repair, and the production of enzymes and hormones necessary for life.
