What role do enzymes play in chemical reactions?

Back

Enzymes lower the activation energy of the reaction, making it easier for the reaction to occur.

Front

What is a plant cell?

Back

A plant cell is a type of cell that is characterized by a rigid cell wall, chloroplasts for photosynthesis, and a large central vacuole.

Front

What kind of molecule encodes genetic information for viruses?

Back

Nucleic acids, such as DNA or RNA, encode genetic information for viruses.

Front

What is a risk associated with genetically identical banana plants?

Back

Genetically identical banana plants are susceptible to a new disease-causing fungus.

Front

What process moves water molecules into and out of cells?

Back

Osmosis is the process that moves water molecules into and out of cells.

Front

What is the function of enzymes in biological systems?

Back

Enzymes act as catalysts to speed up chemical reactions in biological systems.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have them.

Front

What is the primary function of nucleic acids?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What is the significance of the cell wall in plant cells?

Back

The cell wall provides structural support and protection to plant cells.
