What is the general formula of respiration?
C 6 H 12 O 6 + 6 O 2 –> 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.
What is Golgi apparatus short answer?
The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.
What are the two functions of Golgi apparatus?
A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.
How does the Golgi apparatus structure help its function?
The Golgi apparatus serves as a processing center for the exportation of proteins, lipids and other large molecules to their final destinations outside of the cell. Each cisterna is made up of a flattened disk that carries enzymes meant to help or modify the protein cargo that travels through them.
What is the main function of lysosomes Class 9?
CBSE NCERT Notes Class 9 Biology Fundamental Unit of Life. The sac-like structures in a cell surrounded by membrane are called lysosomes. They keep the cells clean by digesting and breaking the outside materials like bacteria, food entering the cell or worn-out cell organelles into small pieces.
What is the shape of a lysosome?
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.
How does a lysosome look like?
In plant cells vacuoles can carry out lysosomal functions. Lysosomes appear initially as spherical bodies about 50-70nm in diameter and are bounded by a single membrane. Several hundred lysosomes may be present in a single animal cell.
Why lysosome is not present in plant cell?
On the other hand, lysosomes are not commonly-found in plant cells. Lysosomes are not needed in plant cells because they have cell walls that are tough enough to keep the large/foreign substances that lysosomes would usually digest out of the cell.
How lysosomes are formed?
Lysosomes form by budding off from the membrane of the trans-Golgi network. Macromolecules (i.e., food particles) are absorbed into the cell in vesicles formed by endocytosis. The vesicles fuse with lysosomes, which then break down the macromolecules using hydrolytic enzymes.
What is the difference between endosome and lysosome?
The main difference between endosome and lysosome is that the endosome is a vacuole which surrounds materials internalized during endocytosis, whereas the lysosome is a vacuole which contains hydrolytic enzymes. Furthermore, endosome forms at the transmembrane of the Golgi apparatus and at the plasma membrane.
What Cell is a real powerhouse?
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
Which enzyme is present in lysosomes?
Lysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. Lysosomal enzymes are synthesized in the endoplasmic reticulum (ER), are transported to the Golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label.
How many enzymes are present in lysosomes?
50 different
