Which organelle is a sac used to store food enzymes and other materials needed by a cell?

The vacuole is a large, round sac found in the cytoplasm. It stores water, food, wastes, or other materials needed by the cell.

What organelle contains substances that break down food particles?

Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids.

What organelle digests vesicles?

A lysosome (/ˈlaɪsəˌsoʊm/) is a membrane-bound organelle found in many animal cells. They are spherical vesicles that contain hydrolytic enzymes that can break down many kinds of biomolecules.

Can digest food particles or old worn out organelles?

Lysosomes
Lysosomes are organelles that contain digestive enzymes (acid hydrolases). They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.

What do vesicles do?

Vesicles can help transport materials that an organism needs to survive and recycle waste materials. … Vesicles also help store and transport materials such as proteins, enzymes, hormones, and neurotransmitters. They are a small but essential part of biological systems and processes such as: digestion and metabolism.

Are vesicles single membrane-bound?

Single- or double-membrane-bound vesicles, including outer-inner membrane vesicles, were observed both inside and outside the cells.

What digests excess or worn-out?

Lysosome
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

What structure digests worn-out organelles and cell debris?

Lysosomes are membrane-enclosed organelles that function as the digestive system of animal cells, serving both to degrade materials taken up from outside the cells and to digest the cells’ own worn-out components.

What is the name of the process by which worn-out organelles are digested by lysosomes?

autophagy. autophagy, also called autophagocytosis, the degradation of worn, abnormal, or malfunctioning cellular components that takes place within organelles known as lysosomes.

What assembles components of the cell membrane and modifies some proteins?

The endoplasmic reticulum is where lipid components of the cell membrane are assembled, along with proteins and other materials that are exported from the cell. … Newly made proteins leave these ribosomes and are inserted into the rough ER where they may be chemically modified.

Which organelle packages proteins into vesicles for transport to the cell membrane?

The Golgi apparatus
The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell. The Golgi apparatus is found close to the nucleus of the cell, where it modifies proteins that have been delivered in transport vesicles from the RER.

What part of the cell modifies proteins chemically then repackages them?

chapter 7-eukaryotic cell structure and function
A B
golgi apparatus modifies proteins chemically, then repackages them
chloroplast contains inner membranes arranged in stacks of membranous sacs called grana
plastids plant organelles that store starches or lipids or that contain pigments

What organelle modifies proteins and is the site where ribosomes are attached?

rough endoplasmic reticulum
rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.

What organelle modifies carbohydrates?

The smooth endoplasmic reticulum (Fig. 1.5A) is associated with carbohydrate metabolism and many other metabolic processes, including detoxification and synthesis of lipids, cholesterol and organic compounds.

What part of the cell assembles amino acids to create proteins?

Ribosome
Eukaryotes
Organelle Function
Ribosome Assembles amino acids to create proteins
Nucleus Contains DNA, which controls the functions of the cell and production of proteins
Nucleolus Found inside the nucleus and produces ribosomes

Which of these structures stores modifies and packages products quizlet?

Which of these structures stores, modifies, and packages products? The Golgi apparatus modifies, stores, and packages products of the ER.

What modifies and sorts proteins in an animal cell?

The Golgi apparatus modifies, sorts, and packages proteins and other materials from the ER for storage in the cell or release outside the cell. From the Golgi apparatus, proteins are “shipped” to their final destination inside or outside the cell. Plants and some other organisms contain chloroplasts.

Which of the following organelles modifies proteins that have already been synthesized?

The endoplasmic reticulum (ER) is a series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids.
