About This Document

Biology helps our understanding of the living world and the various species that inhabit it, as well as how they function, evolve, and interact. The cell – its structure and function, cell transport and cellular energy, and how cells proliferate – are all significant topics in this course. The students will learn about genetics and DNA. There are other units on ecology and evolution.

1GENERAL BIOLOGYAnswer 1:Cheese sandwich comprises of three important nutrients other than vitamins and minerals. Theyare carbohydrate in the form of wheat starch present in the bread. Besides, cheese containsprotein and fat. The main process of their digestion is:CARBOHYDRATE:A.Starch digestion begins in the mouth by ptyalin which is salivary alpha amylase.B.It hydrolyses starch into alpha dextrin.C.This is then broken in to the maltose and malto-triose form with the help of the gluco-amylase (alpha dextrinases).D.The products of the ptyalin and that of glucoamylase are further broken down intocorresponding monosaccharide by maltase, isomaltase, sucrase and lactase in the brushborders of small intestine (Bernardi and Sattin 2015).E.Absorption occurs from the epithelium of the small intestine consisting of villi by activetransport.F.After assimilation they are transported to blood.

2GENERAL BIOLOGYPROTEINA.Stomach helps in the production of hydrochloric acid which helps in the activation of theprotein digestionB.Stomach secretes an enzyme called the pepsin as well as the protease which helps in theremoval of bonds that holds together the long chains of amino acids of the proteins.C.The pancreas helps in the release of the trypsin and chymotrypsinD.All of them enter the small intestine where proteins form polypeptidesE.Here they are further broken down into the amino acids by various exopepeptidases anddipeptidases (Santos et al. 2013).F.Amino acids are absorbed form the small intestine G.They are assimilated and transported through blood to cellsFATS:A.Its starts in the mouth where some form of lingual lipase initiates fat digestion formingdiglycerides from short chain lipids.B.Fats are mainly digested in small intestineC.Presence of fat in small intestine initiates production if hormones which stimulates bileform liver and pancreatic amylase form pancreasD.Emulsification and absorption of fatty acids (Mata-Alvarez et al. 2014)E.Assimilated and transported to cells.
