The inner membrane of mitochondria is folded becausea)it has no space ...
WE KNOW THAT MITOCHRONDRIA ARE POWER HOUSE OF CELL. WHICH MEANS THAT IT IS THE ORGANEL WHICH PRODUCES ENERGY IN FORM OF ATP. BUT MITOCHONDRIA IS VERY SMALL UNIT THERE FOR IT IS NOT EASY TO PRODUCE MORE ATP FOR WHOLE CELL DUE TO LACK OF SURFACE. SO BECAUSE OF THAT MITOCHONDRIAS INNER WALL IS HIGHLY FOLDED
WHICH INCREASES THE SURFACE AREA FOR ATP GENERATION

The inner membrane of mitochondria is folded becausea)it has no space ...
The inner membrane of mitochondria is folded because:
1. To Increase Surface Area:
The folds in the inner membrane of mitochondria, known as cristae, serve to increase the surface area available for chemical reactions. This increased surface area allows for more proteins and enzymes to be embedded in the membrane, enhancing the efficiency of processes such as cellular respiration.
2. Enhanced Functionality:
The increased surface area provided by the folds allows for a greater number of proteins involved in electron transport chain and ATP synthesis to be present in the inner membrane. This, in turn, enhances the functionality of the mitochondria in producing energy for the cell.
3. Optimizing ATP Production:
The folding of the inner membrane into cristae enables the mitochondria to optimize the production of ATP (adenosine triphosphate), which is the main energy currency of the cell. The increased surface area facilitates the electron transport chain reactions that generate ATP.
4. Space Efficiency:
While the folding of the inner membrane may seem to reduce the overall space inside the mitochondria, it actually serves to maximize the utilization of the available space. The cristae provide a compact way to increase the surface area without significantly expanding the volume of the mitochondria.
In conclusion, the folding of the inner membrane of mitochondria into cristae is a crucial adaptation that allows for increased surface area, enhanced functionality, optimized ATP production, and space efficiency within the organelle.

Read the text carefully and answer the questions:Cell organelles are enclosed by membranes. Cell organelles are the endoplasmic reticulum, Golgi apparatus, lysosomes, mitochondria and plastids. The endoplasmic reticulum (ER) is a large network of membrane-bound tubes and sheets. It looks like long tubules or round or oblong bags. There are two types of ER rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). RER looks rough under a microscope because it has particles called ribosomes attached to its surface. The ribosomes, which are present in all active cells, are the sites of protein manufacture. The Golgi apparatus, first described by Camillo Golgi, consists of a system of membrane-bound vesicles arranged approximately parallel to each other in stacks called cisterns.Q.Find out the correct sentence about the Endoplasmic reticulum.I. Enzymes packed in lysosomes are made through RER.II. Rough endoplasmic reticulum and smooth endoplasmic reticulum produce lipid and protein respectively.III. The endoplasmic reticulum is related to the destruction of the plasma membrane.IV. The SER helps in the manufacture of fat molecules or lipids.
