cytoplasmic contents within the lysosome. This mechanism is a form of adaptation to cellular stress such as starvation‚ trophic factor deprivation‚ hypoxia‚ endoplasmic reticulum (ER) stress and oxidative stress (Levine & Abrams‚ 2008). Through adaptation‚ it allows the prevention of cell death. There are three types of autophagy: macroautophagy‚ microautophagy‚ and chaperone-mediated autophagy (CMA). They all are involved in the degradation of cytosolic constituents in the lysosome. Through selective and

Cells are made of many organelles‚ these include the Nucleus‚ DNA‚ Ribosomes‚ Lysosomes‚ Mitochondrion‚ Vacuoles‚ Cytoplasm‚ Endoplasmic‚ Golgi‚ and the Cell Membrane. There is one specific job of each organelle in a cell. The Nucleus is basically the control

aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole a water-filled volume enclosed by a membrane known as the tonoplast which maintains the cell’s turgor (provide structural support) and controls movement of molecules between the cytosol and sap. Stores useful material and digests waste proteins and organelles. The liquid inside the vacuole is known as cell sap‚ and its chemical composition usually is markedly different from that of the surrounding

1. water molecules have +0 charged ends and can form weak hydrogen bonds . water is said to be a dipolar molecule. 2. The basic uits of CO2 are monosaccharides ‚ characterized by the number of carbon atoms‚ e.g pentose sugars have 5 carbons 3. Two monossaccharids can link together to form a disaccharide . the bond between them is a glycosidic linkage formed in a condensation reaction 4. Starch is a polysaccharide composed of amylose and amylopectin. Its main function is as a storage

When molecules move from a low to high concentration it is called moving AGAINST the concentration gradient. When the concentration of a solute is the same throughout a system‚ the system is at EQUILIBRIUM. What kind of transport DOES NOT require energy? PASSIVE What kind of transport requires

Introduction Genetics: the science‚ which deals with the principles of heredity and variation. Heredity: transmission of characters from parents to their off spring. Variation: Differences for various characters among the individuals of the same species. Types of variation: 1. Environmental and 2. Hereditary 1. Heredity variation: Variation observed among the individuals of the same species due to difference in their genetic constitution is termed as heredity variation. 2. Environmental variation:
