 Class 11 Biology Plant Physiology Notes PDF | CBSE & NEET NEET Biology Notes ,( Line-by-Line Explanation) Plant Physiology in Flowering Plants – Understanding Photosynthesis, Respiration, Growth, and Environmental Factors (CBSE Class 11 Biology) Introduction to Plant Physiology Original Line 1: "The description of structure and variation of living organisms over a period of time, ended up as two, apparently irreconcilable perspectives on biology." Easy Notes: Biology studies the structure (body form) and variation (differences) of living organisms. Scientists studied living organisms in two different ways . At first, these two ways looked very different (irreconcilable) . Irreconcilable = Difficult to combine or match. NEET Point: Biology has two major approaches to study life. Original Line 2: "The two perspectives essentially rested on two levels of organisation of life forms and phenomena." Easy Notes: These two approaches are based on t...

  Small Molecular Weight Organic Compounds in Living Tissues (NEET Biology Notes) Biomolecules in Living Tissues: Complete NEET study chart covering carbohydrates, amino acids, lipids, nucleotides, DNA and RNA. Chapter: Biomolecules -Dr.Sanjaykumar Pawar  Introduction Living organisms are made up of different types of organic molecules . These molecules are called biomolecules because they are essential for life. The four major groups of biomolecules are: Carbohydrates (Sugars) Proteins (Amino acids) Lipids (Fats and Oils) Nucleic Acids (DNA & RNA building blocks) These molecules perform different functions such as providing energy, building body tissues, storing food, and carrying genetic information. 1. Carbohydrates (Sugars) What are carbohydrates? Carbohydrates are the main source of energy in living organisms. They are made up of three elements: Carbon (C) Hydrogen (H) Oxygen (O) General formula: (CH₂O)ₙ Examples shown in the figure (A) Glucose Molecular Formula: C₆...

 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...
