mitochondrial disorders
What do you think will happen if one of those organelles does not function properly?
Answer.
The cell will rupture
. Each and every cell organelle has its own function in the cell without which the metabolism of the cell be affected.
How does an organelle affect its function?
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles
serve specific functions to keep a cell alive
.
What human diseases are caused by defective cell organelles?
Malfunctioning mitochondria have been linked to
diabetes, heart disease, Alzheimer’s disease, Parkinson’s disease and even normal aging
. “If we can learn more about the rare mitochondrial disorders, the findings could have implications for understanding more common diseases,” says Dr.
What are the disorders and diseases that result from the malfunction of the cell during the cell cycle?
These diseases include
neurodegenerative, haematological, autoimmune, cardiovascular, metabolic and development-associated disorders, malignant and premalignant disease, atherosclerosis, ischaemic injury and bacterial and viral infections
.
Why are organelles important to the cell?
Why are organelles so important? Organelles are important because
they help compartmentalize the cell for different functions
. Different types of jobs can be specialized and regulated as they are combined to different parts of the cell.
What is an organelle and why is it important?
An organelle is
a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body
. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
What is the advantage of having organelles?
Organelles
contribute to efficiency in eukaryotic cells
because they concentrate the biochemicals needed for chemical reactions so that the reactions proceed more rapidly, leading to efficiency. Also, because of organelles, a eukaryotic cell can get along with high concentrations of biochemicals only in certain areas.
How do organelles work together to maintain all life processes in a unicellular organism?
Cell organelles must work together to
carry out protein synthesis, utilize proteins within the cell, and transport them out of the cell
.
How are organelles in a cell like organs in a human body?
Like organs in an organism,
each organelle has a specific function in a cell
. All of the organelles work together to carry out the functions of the cell as a whole, just as organs do to an organism. For example, mitochondria are the sites of cellular respiration; they provide energy the cell.
What are the advantages of the presence of organelles in eukaryotic cells?
Organelles
contribute to efficiency in eukaryotic cells because they concentrate the biochemicals needed for chemical reactions so that the reactions proceed more rapidly, leading to efficiency
. Also, because of organelles, a eukaryotic cell can get along with high concentrations of biochemicals only in certain areas.
What organelle is affected by Pompe disease?
The defect results in a build-up of glycogen in
the lysosome
, a saclike storage organelle in the cell that acts as a waste-disposal system, leading to muscle weakness, organ damage including the brain, and possible death.
What are cellular organelle diseases?
Four well-defined groups of genetic diseases in man can now be recognized in which the functions of an intracellular organelle are impaired:
lysosomal storage diseases, mitochondrial disorders, endoplasmic reticulum storage diseases, and peroxisomal diseases
.
What organelle is affected by Alzheimer’s disease?
Mitochondria
are well-known cellular organelles widely studied in relation to a variety of disease states, including Alzheimer’s disease.
What happens to organelles when mitochondria malfunctions?
When the mitochondria are defective, the cells do not have enough energy.
The unused oxygen and fuel molecules build up in the cells and cause damage
.
How do problems in cells lead to disease?
How do problems in cells lead to disease?
Changes to the genes inside a cell, called mutations, can alter the cell’s ability to divide, make proteins, remove waste, or perform other tasks
. These genetic mutations can lead to birth defects, cancer, and other diseases.
What are the negative consequences when cell division goes wrong?
Disruption of normal regulation of the cell cycle can lead to
diseases such as cancer
. When the cell cycle proceeds without control, cells can divide without order and accumulate genetic errors that can lead to a cancerous tumor .
What is the most important organelle in a cell?
Cell membrane
is the most important organelle, it surrounds the living cells.
Why do some organelles have membranes and some do not?
Membrane-bound organelles are surrounded by a plasma membrane to keep their internal fluids separate from the cytoplasm of the rest of the cell.
Non-membrane bound organelles are more solid structures that are not fluid-filled, so they have no need for a membrane
.
How can analyzing the relationships of cell organelles help us to understand living things?
How can analyzing the relationships of cell organelles help us to understand living things?
We study and analyze cells because they are the basis for life
. We are all made up of cells and it is important that we understand the function of all of the organelles present in cells so we know how cells work.
What organelle can you live without?
You can’t survive without
mitochondria
, the organelles that power most human cells. Nor, researchers thought, can any other eukaryotes—the group of organisms we belong to along with other animals, plants, fungi, and various microscopic creatures.
What are the benefits of having organelles How do these benefits relate to cell size?
Larger cells have organelles to help them function
. When the surface area to volume ratio gets too small, the cell can no longer grow and needs organelles to help transport materials around the cell. Organelles are tiny compartments that ensure the cell no longer has to rely on the lengthy process of diffusion.
Why is it important for organelles to have their own membranes?
Like the plasma membrane, organelle membranes function
to keep the inside “in” and the outside “out.”
This partitioning permits different kinds of biochemical reactions to take place in different organelles.
What are some of the benefits of having some of the cellular organelles enclosed by a membrane similar to the cell plasma membrane?
What is the benefit of having some of the cellular organelles enclosed by a membrane similar to the plasma membrane? The isolation of the internal contents of membrane-bound organelles
allows them to manufacture or store secretions, enzymes or toxins that could adversely affect cytoplasm in general
.
