Mitochondria
, the powerhouse of the cell, convert sustenance into energy, fueling the cell’s activities. In addition to power, mitochondria also produce reactive oxygen species, byproduct molecules primed to help facilitate communication among the other units in the cells.
What is the name of the powerhouse of the cell?
Work on
mitochondria
did not stop in the 1950s after it was named “the powerhouse of the cell.” Subsequent studies throughout the rest of the 20th century identified the mitochondria as an incredibly dynamic organelle involved in multiple cellular processes in addition to energy production.
What is the powerhouse of the cell called Class 8?
Answer:
Mitochondria
are called the ‘powerhouses’ of the cells because the energy generating process of the body i.e., cellular respiration, takes place in mitochondria.
Why mitochondria is called the powerhouse of the cell?
Mitochondria are often called the “powerhouses” or “energy factories” of a cell
because they are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule
. … Cellular respiration is the process of making ATP using the chemical energy found in glucose and other nutrients.
Is nucleus the powerhouse of the cell?
The nucleus is
the control center of all cells in the body
and controls the cell’s shape and processes. … Mitochondria are the powerhouse of the cell. They create energy using cellular respiration.
Which is called the suicidal bags of cell?
Lysosomes
are called suicide sacks. They are produced by the Golgi body. They consist of a single membrane surrounding powerful digestive enzymes. It acts as the “garbage disposal” of the cell by breaking down cell components that are no longer needed as well as molecules or even bacteria that are ingested by the cell.
Which is the smallest cell?
The smallest cell is
Mycoplasma (PPLO-Pleuro pneumonia like organims)
. It is about 10 micrometer in size. The largest cells is an egg cell of ostrich. The longest cell is the nerve cell.
What is the full form of ATP *?
Adenosine triphosphate
(ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
Which shape is best for cell?
Therefore, if a cell is going to be spherical, it would be best to be
the smallest sphere possible
, because decreasing size increases the surface-to-volume ratio (i.e., the volume decreases faster than does the area that can service it with nutrients).
Who discovered the cell?
Initially discovered by
Robert Hooke
in 1665, the cell has a rich and interesting history that has ultimately given way to many of today’s scientific advancements.
What are the three functions of the mitochondria?
Function. The most prominent roles of mitochondria are to
produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration and to regulate cellular metabolism
. The central set of reactions involved in ATP production are collectively known as the citric acid cycle, or the Krebs cycle.
What is the most important function of mitochondria?
Mitochondria. Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of
the chemical energy needed to power the cell’s biochemical reactions
. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
What is the mitochondria function?
Mitochondria are well known as
the powerhouse of the cell
, and as discussed in the section on Generation of ATP: Bioenergetics and Metabolism, in an active tissue such as heart, they are responsible for generating most of the ATP in the cell.
What is the function of nucleus in a cell?
The nucleus
controls and regulates the activities of the cell
(e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.
Which cells contain nucleus?
The nucleus is an organelle found in
eukaryotic cells
. Inside its fully enclosed nuclear membrane, it contains the majority of the cell’s genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.
Who is the powerhouse of the cell and why?
Cells use a special molecule for energy called adenosine triphosphate (ATP). Thus,
Mitochondria
are called the powerhouse of the cell. They are called so because they produce ATP, an energy-dense molecule responsible for powering most cellular processes in a living organism.
