Keystone Biology Module 1 part 2

What are lysosomes and their function?

• Lysosomes are organelles that contain enzymes to break down waste materials and cellular debris.

• Lysosomes are structures that store genetic information in the cell.

• Lysosomes are responsible for protein synthesis in the cell.

• Lysosomes are involved in energy production within the cell.

How do antibiotics affect bacterial cells?

• Antibiotics can enhance the growth of bacteria.

• Antibiotics can disrupt the cell wall of bacteria, leading to cell lysis and death.

• Antibiotics have no effect on bacterial cells.

• Antibiotics can only affect viral cells.

What is the role of phospholipids in cell membranes?

• Phospholipids form the bilayer of cell membranes, providing a barrier and allowing for fluidity and flexibility.

• Phospholipids act as enzymes to speed up cellular reactions.

• Phospholipids are responsible for the synthesis of proteins in the cell.

• Phospholipids store genetic information within the cell.

What is homeostasis?

• The process by which living organisms maintain a stable internal environment despite external changes.

• The ability of an organism to adapt to new environments quickly.

• The mechanism by which organisms reproduce and pass on their genes.

• The way organisms obtain energy from their surroundings.

What is the function of the Golgi apparatus in eukaryotic cells?

• The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

• The Golgi apparatus is responsible for energy production in the cell.

• The Golgi apparatus synthesizes ribosomes for protein synthesis.

• The Golgi apparatus stores genetic information in the cell.

What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus and membrane-bound organelles, while eukaryotic cells lack these features.

• Prokaryotic cells are larger and more complex than eukaryotic cells.

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

• Prokaryotic cells reproduce sexually, while eukaryotic cells reproduce asexually.

What is the role of ribosomes in protein synthesis?

• Ribosomes are the sites where amino acids are assembled into proteins based on the sequence of mRNA.

• Ribosomes are responsible for the replication of DNA.

• Ribosomes transport proteins to the cell membrane for secretion.

• Ribosomes are involved in the breakdown of fatty acids.

What role do ATP molecules play in protein synthesis?

• ATP molecules provide the energy required for the synthesis of proteins.

• ATP molecules act as building blocks for protein structure.

• ATP molecules are involved in the transport of proteins across cell membranes.

• ATP molecules serve as a source of genetic information for protein synthesis.

How do cell walls protect bacterial cells?

• Cell walls provide energy for bacterial metabolism.

• Cell walls provide structural support and protect bacterial cells from environmental stress and osmotic pressure.

• Cell walls allow for the movement of nutrients into the cell.

• Cell walls are primarily responsible for bacterial reproduction.

What is the relationship between cellular respiration and energy production?

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

• Cellular respiration occurs only in plants and not in animals.

• Cellular respiration is the process of converting sunlight into chemical energy.

• Cellular respiration does not involve any gas exchange.
