Lysosomes range in size from 0.1 μm to 1.2 μm. With a pH of 4.5–5.0, the lysosomes’ interior is acidic compared to the somewhat basic cytoplasm (pH 7.2). The lysosomal membrane protects the cytosol, and thus the entire cell, from the lysosomal degradative enzymes. 

If you face conductive hearing loss, you will hear the bone conduction (BC) sound for a longer period with a Length of BC limit than you will hear the air conduction sound with AC limit. When a person has deafness, air conduction is heard longer than bone conduction, but not twice as long. BC testing is performed by attaching an oscillator to the mastoid process and determining the threshold at the same tones. Occasionally, masking noise is employed in the non-test ear to prevent it from participating in the test.

About Lysosomes

The lysosome is an organelle that is present in a large number of animal cells. They are spherical vesicles containing hydrolytic enzymes capable of degrading a wide variety of biomolecules. A lysosome contains a unique composition of the membrane and lumenal proteins. Apart from polymer degradation, the lysosome participates in various cellular functions, such as secretion, plasma membrane repair, apoptosis, cell signaling, and energy metabolism.

Numerous elements of animal cells are recycled by relocating them inside or embedding them in membrane segments. For example, during endocytosis (more precisely, macropinocytosis), a piece of the cell’s plasma membrane pinches off to create vesicles that eventually fuse with an organelle inside the cell. Lysosomes contain a range of enzymes that enable the cell to degrade the biomolecules it ingests, such as peptides, carbohydrates, and lipids (lysosomal lipase)—the enzymes involved for this hydrolysis function optimally in an acidic environment.

About Bone Conduction (BC)

Bone conduction (BC) is the process by which sound is transmitted to the inner ear predominantly via the skull’s bones, allowing the hearer to experience auditory material without closing the ear canal. Bone conduction transmission happens continuously as sound waves vibrate bone, specifically the bones in the skull. However, the average person has difficulty distinguishing between sound sent through bone and sound transmitted through the air via the ear canal.

Intentional sound transmission through bone can be employed with normal hearing individuals as an option for specific types of hearing treatment. In general, bone is better at transmitting low-frequency noises than high-frequency sounds. Bone conduction is one of the reasons that when a person’s voice is recorded and played back, it sounds different to them. The skull conducts lower level frequencies better than air, people experience their voices as lower and fuller than others, and a recording of one’s voice typically sounds higher than expected.


Lysosomes work as the cell’s waste disposal mechanism by digesting spent components in the cytoplasm from within and outside the cell. Lysosomes are from 0.1 to 1.2 μm in size. Endocytosis is the process by which material from the outside of the cell is taken up. At the same time, autophagy is the process by which material from the inside of the cell is digested. Organelles vary significantly in size—the largest can be more than ten times the smallest size. The theory of Cell for Lysosomes Study was introduced by Christian de Duve, a Belgian biologist who was later awarded the 1974 Nobel Prize in Physiology or Medicine.
