 Enzyme Co-factors: Apoenzyme, Holoenzyme & Types Explained  Co-factors help enzymes become active by combining with apoenzymes to form functional holoenzymes. -Dr.Sanjaykumar Pawar  Co-factors (NCERT Class 11 Biology) Line-by-Line Explanation Notes (NEET Preparation) 6. Co-factors Introduction to Co-factors Line: Enzymes are composed of one or several polypeptide chains. Explanation: Enzymes are mainly made up of proteins . Proteins are made up of long chains of amino acids called polypeptide chains . Some enzymes contain only one polypeptide chain, while others contain multiple chains. Line: However, there are a number of cases in which non-protein constituents called co-factors are bound to the enzyme to make the enzyme catalytically active. Explanation: Some enzymes cannot work alone. They require an additional non-protein component called a co-factor . Co-factors attach to enzymes and help them perform their catalytic activity. Without the co-...

Factors Affecting Enzyme Activity Class 11 Biology Notes | CBSE & NEET Factors Affecting Enzyme Activity ( NEET Note- Explanation)  Factors Affecting Enzyme Activity showing the effects of temperature, pH, substrate concentration, Vmax, and competitive inhibition for CBSE Class 11 and NEET Biology. -Dr.Sanjaykumar Pawar  What are Factors Affecting Enzyme Activity? Definition: Factors affecting enzyme activity are the conditions that can increase or decrease the speed of enzyme-catalysed reactions. Main Factors Temperature 🌡️ pH Substrate Concentration Inhibitors (Specific Chemicals) NEET Tip: Remember these four factors as "TPSI" T = Temperature P = pH S = Substrate concentration I = Inhibitors Line-by-Line Explanation Line 1 "The activity of an enzyme can be affected by a change in the conditions which can alter the tertiary structure of the protein." Easy Meaning Enzymes are proteins. Proteins have a special 3D (tertiary) struc...

 Nature of Enzyme Action Class 11 Biology Notes PDF | CBSE & NEET Nature of Enzyme Action (Easy NEET Notes) Nature of Enzyme Action: Step-by-step process showing enzyme-substrate complex formation, catalysis, and product release for CBSE Class 11 and NEET Biology. -Dr.Sanjaykumar Pawar  What is an Enzyme? Enzyme (E) = A biological catalyst that speeds up chemical reactions. Substrate (S) = The substance on which the enzyme acts. Product (P) = The final substance formed after the reaction. Basic Enzyme Reaction E + S → ES → EP → E + P Meaning of each step: E + S = Enzyme meets the substrate. ES = Enzyme-Substrate Complex is formed. EP = Enzyme-Product Complex is formed after the reaction. E + P = Product is released and the enzyme remains unchanged. NEET Point: The enzyme is not consumed during the reaction and can be used again. Line-by-Line Explanation Line 1: "Each enzyme (E) has a substrate (S) binding site in its molecule." Easy Meaning...

  Chemical Reactions and Enzymes – Easy Line-by-Line Notes (NEET Beginner Level) Chemical reactions and enzymes explained with simple diagrams for CBSE Class 11 Biology students. 1. What is a Chemical Reaction? A chemical reaction is a process in which old chemical bonds break and new bonds are formed . As a result, new substances (products) are produced. Example: Ba(OH)₂ + H₂SO₄ → BaSO₄ + 2H₂O NEET Point: Chemical reaction = Breaking + Formation of bonds . 2. Types of Changes in Chemical Compounds A. Physical Change Only the shape, size, or state changes. No chemical bonds are broken or formed. No new substance is produced. Examples Ice → Water Water → Water vapour Cutting paper Breaking glass Remember: Physical change = No new substance. B. Chemical Change Old bonds break and new bonds form. A new substance is produced. This process is called a chemical reaction . Examples Burning wood Rusting of iron Digestion of food Hydrolysis of starc...
