1st Study Flashcard

Front

What is the primary function of proteins in a human cell?

Back

Proteins catalyze chemical reactions inside the cell and allow for the transport of certain molecules into and out of the cell.

Front

What is the process by which DNA encodes traits for organisms?

Back

DNA is transcribed into mRNA, which is then translated into proteins.

Front

What is the role of ATP in cellular processes?

Back

ATP provides energy for chemical reactions in the cell.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

The organization of the genetic material; prokaryotic cells have circular DNA, while eukaryotic cells have linear DNA organized in chromosomes.

Front

Which two biomolecules are essential for building lean muscle and providing energy?

Back

Proteins and carbohydrates.

Front

What is the function of lipids in a cell?

Back

Lipids serve as structural components of cell membranes and store energy.

Front

How does mRNA relate to DNA and proteins?

Back

mRNA is synthesized from DNA and serves as a template for protein synthesis.

Front

What is the significance of the cell membrane?

Back

The cell membrane regulates the movement of substances in and out of the cell.

Front

What is the role of nucleic acids in organisms?

Back

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

Front

What is the difference between a prokaryotic and a eukaryotic cell?

Back

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