Day 2 Review

Which organelle is responsible for packaging and transporting proteins?

• Ribosome

• Endoplasmic Reticulum

• Golgi apparatus

• Lysosome

What is the function of ribosomes?

• Energy production

• Protein synthesis

• DNA replication

• Cell division

What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus; eukaryotic cells lack a nucleus.

• Prokaryotic cells are larger than eukaryotic cells.

• Prokaryotic cells lack a nucleus; eukaryotic cells have a nucleus.

• Prokaryotic cells are more complex than eukaryotic cells.

What happens when temperature increases too much in an enzyme-catalyzed reaction?

• The enzyme denatures.

• The reaction rate increases indefinitely.

• The enzyme becomes more active.

• The substrate concentration decreases.

What is the role of the nucleus in a cell?

• It stores genetic information.

• It produces energy for the cell.

• It helps in protein synthesis.

• It regulates cell division.

What is the structure of a cell membrane?

• A phospholipid bilayer with embedded proteins.

• A single layer of phospholipids.

• A rigid cell wall made of cellulose.

• A network of carbohydrates and lipids.

What is denaturation in proteins?

• The process where proteins lose their structure and function due to external stress.

• The process of proteins gaining additional functional groups.

• The process where proteins are synthesized from amino acids.

• The process of proteins folding into their native structure.

What is the function of mitochondria?

• Energy production through cellular respiration.

• Protein synthesis in the cell.

• Storage of genetic information.

• Detoxification of harmful substances.

Why can proteins perform so many different functions?

• Their shape determines their function.

• They are made of different amino acids.

• They can be found in various locations in the cell.

• They are involved in energy production.

What is the monomer of nucleic acids?

• Amino acids

• Nucleotides

• Fatty acids

• Monosaccharides
