Peroxisomes and Its Functions

Peroxisomes or microbodies are the membrane minimal vesicles like the lysosomes. Unlike lysosomes, peroxisomes are pinched off from endoplasmic reticulum and not from the Golgi apparatus Peroxisomes consist of some oxidative enzymes such as catalase, urate oxidase and D-amino acid oxidase.   Oxidative enzymes, as the name

RNA Structure, Function, Synthesis, Types and Interference

There many types of RNA in a cell Nevertheless, we will focus on the three that are straight related to producing proteins: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). DNA can not produce proteins without their help. The other RNA types play various regulative

Dense Connective Tissue

Like loose connective tissues, dense connective tissues help binding tissues together and offering assistance for organs Nevertheless, dense connective tissue has far less cells and ground substance and more various, thicker, and “denser” protein fibers. These tissues likewise include far less blood vessels than loose connective tissues

Structure of Skeletal Muscle

Skeletal muscles are the organs of the muscular system. They are called skeletal muscles because most of them are attached to bones. A skeletal muscle is composed mainly of skeletal muscle tissue bound together and electrically insulated by connective tissue layers. Individual skeletal muscle cells, called muscle

The Structures, Locations, and Functions of the Sensory Receptors

Sensory receptors for the general senses are widely distributed in the skin, muscles, tendons, ligaments, and visceral organs. Temperature Two types of thermoreceptors are located in the skin. Warm receptors are free nerve endings, which are sensory neuron dendrites, in the deep dermis that are most sensitive
