What breaks down worn-out cell parts mostly in animal cells?

What breaks down worn-out cell parts mostly in animal cells?

Lysosomes
Intercellular Junctions

Cell Component	Function	Present in Animal Cells?
Lysosomes	Digestion of macromolecules; recycling of worn-out organelles	Yes
Cell wall	Protection, structural support and maintenance of cell shape	No
Chloroplasts	Photosynthesis	No
Endoplasmic reticulum	Modifies proteins and synthesizes lipids	Yes

What digests worn-out cell parts waste?

Use the table above to fill in the chart

Structure/Function	Cell Part
Digests excess or worn-out cell parts, food particles and invading viruses or bacteria	Lysosome
Small bumps located on portions of the endoplasmic reticulum	Ribosomes
Provides temporary storage of food, enzymes and waste products	Vacuole

Which two organelles work together to destroy harmful substances in cells?

Lysosomes digest foreign substances that might harm the cell: A macrophage has engulfed (phagocytized) a potentially pathogenic bacterium and then fuses with a lysosomes within the cell to destroy the pathogen.

What breaks down waste and old material in cells?

Lysosomes break down waste products within the cell and transport the remains out of the cell. They contain enzymes that help them do this.

What structure keeps harmful chemicals out of animal cells?

Lysosomes contain enzymes that break down the macromolecules and foreign invaders. Lysosomes are composed of lipids and proteins, with a single membrane covering the internal enzymes to prevent the lysosome from digesting the cell itself.

What contains chemicals that break down food wastes and worn out organelles?

Lysosomes digest food particles, wastes, cell parts, and foreign invaders. Lysosomes are the cell’s clean-up crew. They digest worn-out or damaged organelles, get rid of waste and protect cells from foreign invaders like bad bacteria. Lysosomes are mainly found in animal cells.

What structure keeps harmful chemicals out of the cell?

Lysosomes contain enzymes that break down the macromolecules and foreign invaders. Lysosomes are composed of lipids and proteins, with a single membrane covering the internal enzymes to prevent the lysosome from digesting the cell itself.

What removes harmful substances from a cell?

cell functions

smooth er	removes harmful substances from cell
mitochondria	releases energy in cell
golgi apparatus	prepares proteins for special job
vesicle	carries substances to other parts of the cell
cell wall	stiff structure outside the cell membrane

Are membranous sacs that detoxify harmful chemicals?

Peroxisomes
Peroxisomes are membrane-bound organelles that contain an abundance of enzymes for detoxifying harmful substances and lipid metabolism.

How does the cell get rid of worn out parts?

If there are old worn-out parts in a cell, or too many mitochondria, or poisons, then the lysosome forms a membrane bubble around them, and the enzymes inside the lysosome break these large parts down into small molecules that can fit to get through the cell membrane.

How do cells eliminate waste?

Cells use both diffusion and osmosis to get rid of their wastes. Cells can bias the movement of waste molecules out of and away from themselves. Another way is the make an oily molecule water-soluble, so that it can be dissolved in water and flushed away in the bloodstream.

How does the cell membrane control food and waste?

Large storage container for water, food, and waste only in plant cells Cell membrane Made of two layers of phospholipids. Controls what moves in and out of the cell Mitochondria Where food is broken down during cellular respiration so ATP can be realeased to be used by the cell Smooth er

What happens to a cell when the lysosome is damaged?

If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis. Now, the lysosome is a specific type of organelle that’s very acidic.

Is the cell membrane a large storage container for food?

Large storage container for water, food, and waste only in plant cells Cell membrane Made of two layers of phospholipids also controls what moves in and out of the cell

What kind of enzymes break down large molecules?

Those enzymes are called hydrolytic enzymes, and they break down large molecules into small molecules. For example, large proteins into amino acids, or large carbohydrates into simple sugars, or large lipids into single fatty acids.
