Define the term enzyme. State the role of saliva in human digestive system. |
| Answer» Enzymes are macromolecular biological catalysts. Enzymes accelerate chemical reactions. The molecules upon which enzymes may act are called substrates and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called enzymologyVisit www.ethicalabhishek.tk Don\'t worry I am also in class 10 th Saliva is a fluid substance formed in the mouths of animals, secreted by the salivary glands. Human saliva comprises 99.5\u2060% water plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as amylase and lipase), antimicrobial agents such as secretory IgA and lysozyme.[1] The enzymes found in saliva are essential in beginning the process of digestion of dietary starches and fats. These enzymes also play a role in breaking down food particles entrapped within dental crevices, thus protecting teeth from bacterial decay.Furthermore, saliva performs a lubricative function, wetting food and permitting the initiation of swallowing, and protecting the mucosal surfaces of the oral cavity from desiccation. | |

|
Answer» Synapse is a junction or space between two neurons i.e.between the axon of one neuron and dendrite of other neuron.a chemical named acetylcolin is released here which changes the electrical impulse coming from axon into chemical impulse which is again converted into electrical impulse at the dendrite of other neuron. synapse is a gap between two newrons,there are many newrons present at every part of the body,these newrons are responsible for transferring of various information,the information cant transfer between synapse(gap) so it releases chemical then the information goes through it and after this the information again attached with other newron for tansferring information ex- if we have to move our hand newrons helps us to send information and we can move our hand easily |

What is reflex action? Explain the role of brain in reflex action? |
|
Answer» Reflex action is the sudden and immediate response by our body. There is no important role of brain in reflex action it only receives the message send by sensory neurons and does not play any function. Thanku Rohit kumar & Rehan Chauhan Suddenly our hand fall on a hot subject this message goes our spinal cord from sensary nerve and our spinal cord gives message withdrawl of our hand from motor nerves Its contol by spinal cord The simplest form of response in human body is called reflex action Reflex action are those actions which happens suddenly without knowing ex- if the dirt come inside our eyes our eyes suddenly close the role of brain in reflex action is thatThe sensory nerves that detect the heat are connected to the nerves that move the muscles of the hand. Such a connection of detecting the signal from the nerves and responding to it quickly is known as reflex arc. Reflex arcs are formed in the spinal cord and the information reaches the brain and brain responses to it. |
