Biology Fall Final Practice

Front

What is the function of ribosomes in cells?

Back

Ribosomes are responsible for synthesizing proteins, including enzymes, by translating messenger RNA (mRNA) into polypeptide chains.

Front

What type of macromolecule is responsible for storing and transmitting genetic information?

Back

Nucleic acids, such as DNA and RNA, store and transmit hereditary information.

Front

How is chemical energy released from food molecules?

Back

Chemical bonds in food molecules are broken, releasing energy that cells use to produce ATP.

Front

Why does glycolysis not yield four molecules of ATP despite synthesizing four ATP molecules?

Back

Two ATP molecules are required to start the glycolysis process, resulting in a net gain of two ATP.

Front

What inference did Camille make about her plant's drooping leaves?

Back

Camille inferred that the plant needed water based on her observation of the drooping leaves.

Front

What is the role of the pancreas in digestion?

Back

The pancreas produces digestive enzymes that help break down food in the digestive system.

Front

What are the main components of nucleic acids?

Back

Nucleic acids are made up of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the primary function of enzymes in biological systems?

Back

Enzymes act as catalysts to speed up chemical reactions in the body without being consumed in the process.

Front

What is ATP and why is it important for cells?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

What is the difference between a hypothesis and an inference?

Back

A hypothesis is a testable prediction based on observations, while an inference is a conclusion drawn from past experiences and observations.
