- Photosynthesis equation: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
- Respiration equation: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy (ATP)
- Transpiration rate = (Mass of water lost)/(Time taken) × (Area of leaf)
- Blood pressure = (Cardiac output × Peripheral resistance)
- Breathing rate = (Number of breaths)/(Time taken)
- Human digestive system equation: Carbohydrates → Glucose → Energy (ATP)
- Plant growth equation: Aux∈ → Cell elongation → Cell division
- Osmosis equation: Water potential = (Solute potential + Pressure potential)
- Human excretory system equation: Waste removal = (Kidney function + Liver function)
- Aerobic respiration equation: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 36ATP
🪤 The 5 Mistakes That Cost Marks
- Not understanding the difference between photosynthesis and respiration
- Forgetting the equation for transpiration rate
- Not knowing the human digestive system equation
- Confusing osmosis with diffusion
- Not being able to expla∈ the human excretory system equation
✏️ 3 Solved PYQs
- What is the role of mitochondria ∈ cellular respiration: Mitochondria are the site of aerobic respiration, where glucose is broken down to produce ATP
- Describe the process of transpiration: Transpiration is the process by which water is transported through a plant, from the roots to the leaves, and is then lost into the air as water vapor
- What is the difference between systolic and diastolic blood pressure: Systolic blood pressure is the pressure ∈ the arteries when the heart beats, while diastolic blood pressure is the pressure ∈ the arteries when the heart rests
🧠 The One Thing Most Students Get Wrong
- Most students get confused between the terms active transport and passive transport
- Active transport requires energy to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules down their concentration gradient
- Understanding this concept is crucial for understanding various life processes, including photosynthesis, respiration, and transpiration
👁️ Ayush's Note
- To score well ∈ the exam, it is essential to have a thorough understanding of the life processes, including photosynthesis, respiration, transpiration, and human physiology
- Practice drawing diagrams of the human digestive system, excretory system, and plant transport system
- Make sure to learn the equations and formulas, including the photosynthesis equation, respiration equation, and transpiration rate equation
🔁 Last 5 Minutes Box
- Quickly revise the formulas and equations, including the photosynthesis equation and respiration equation
- Go through the diagrams of the human digestive system, excretory system, and plant transport system
- Make sure to remember the difference between active transport and passive transport
- Take a few deep breaths and stay calm, as this will help you to think clearly and answer the questions correctly
