Front

What are lipids?

Back

Lipids are organic molecules that are insoluble in water and include fats, oils, and waxes. They are important for energy storage, insulation, and making up cell membranes.

Front

What role do enzymes play in chemical reactions?

Back

Enzymes catalyze reactions by decreasing the activation energy required for the reaction to occur, thus speeding up the process.

Front

What is the rough endoplasmic reticulum (rough ER)?

Back

The rough ER is a type of endoplasmic reticulum that is studded with ribosomes, which are the sites of protein synthesis. It plays a key role in the production and processing of proteins.

Front

What are the two main reactants of cellular respiration?

Back

The two main reactants of cellular respiration are glucose (C6H12O6) and oxygen (6O2).

Front

In an experiment, what is the independent variable?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable. In the plant growth experiment, it is the type of liquid given to the plants.

Front

What are carbohydrates?

Back

Carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. They are a primary source of energy for living organisms.

Front

What is the function of proteins in the body?

Back

Proteins serve various functions including building and repairing tissues, acting as enzymes, and supporting immune function.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the difference between an independent variable and a dependent variable?

Back

The independent variable is the one that is changed or controlled in an experiment, while the dependent variable is the one that is measured or affected in the experiment.

Front

What are nucleic acids?

Back

Nucleic acids, such as DNA and RNA, are organic molecules that store and transmit genetic information.
