Which major biological molecules make up the plasma membrane?
-proteins, carbohydrates, and nucleic acids
-carbohydrates, lipids, and nucleic acids
-carbohydrates, proteins, and lipids
-lipids, proteins, and nucleic acids
-carbohydrates, lipids, proteins, and nucleic acids
The major difference between diffusion and endocytosis is that ________.
-in endocytosis, the molecules are lipid
soluble; in diffusion, the molecules are water soluble
-in endocytosis, the molecules are water soluble; in diffusion, the molecules are lipid soluble
-in endocytosis, larger particles are engulfed; in diffusion, smaller particles pass through the membrane
-in endocytosis, smaller particles always fuse before or after being engulfed; in diffusion, particles do not fuse
-in endocytosis, smaller particles are engulfed; in diffusion, larger particles pass through the membrane
What part of the cell breaks down macromolecules using digestive enzymes?
lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms.
What part of the cell is responsible for breaking down and?
Other organelles like lysosomes are responsible for digesting and recycling toxic substances and waste. They are embedded with proteins called enzymes, which break down macromolecules, including amino acids, carbohydrates, and phospholipids.
Which of the following organelle is responsible in breaking down waste in the cell?
Lysosomes. The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused.
What is the name of the cellular structure that breaks down macromolecules for recycling or waste disposal?
Lysosomes act as the clean-up crew of the cell. They are filled with enzymes that break down macromolecules into smaller molecules, which are then used to nourish the cell. They can digest peptides, nucleic acids, carbohydrates, and lipids. This is how cells recycle materials like amino acids and glucose.
