Mitochondria Structure And Functions | Powerhouse | Class 11 Biology



Hi Everyone! Welcome To My Channel “Ali Academy Biology Lectures”

About This Video ……………………

In This Video Lecture You Will Learn Basic Concept Of Mitochondria
Mitochondria are very important organelles of eukaryotic cells, because they are involved in the
matrix. These infolds are called cristae. The mitochondrial membranes are similar in structure to
structure vary widely, a mitochondrion is bound by two membranes, the outer membrane is
manufacture and supply of energy to the cell. They are also known as powerhouses of the cell
particles. Mitochondrial matrix contains in it a large number of enzymes, coenzymes and
The inner surface of cristae in the mitochondrial matrix has small knob like structures known as F1
(Fig. 4.13). Under compound microscope they appear to be vesicles, rods or ilaments. Under an
smooth, while the inner membrane forms infoldings into the inner chamber called mitochondrial
self replicating organelle.
The presence of ribosomes and DNA indicates that some proteins are synthesized in them. It is a
other cell membranes. Detailed studies have shown that mitochondria also contain DNA as well as
ribosomes.
electron microscope, they show complex morphology. Although their number, shape and internal
organic and inorganic salts which help in several vital metabolic processes like Kreb’s cycle, aerobic respiration, fatty acid metabolism etc. As a result of these metabolic processes the energy extracted
and the ATP then provides energy to the cell on demand. The size and number of mitochondria
from the organic food is transformed into energy rich compound ATP (adenosine triphosphate),
varies and depends on the physiological activity of the cell.

About This Channel…………………

I make these videos cause I love to draw and connect the complexity of science and medicine into art. I’m not saying. I’m 100% correct in all my videos, but I do try to obtain the information from credible sources.
One-stop destination for all biology lectures.
_ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial
_ The videos are categories under various heading to make the students life simplified
