1. BIOENERGINETICS

2. What is Bioenergetics? Bioenergetics studies how living things get and use energy . It helps us understand how our bodies and cells work . Importance of Energy: Energy is needed for all activities, like moving, growing, and thinking . Without energy, living things can't survive.

3. Sources of Energy: Plants get energy from the sun through photosynthesis . Animals get energy from the food they eat . Cellular Respiration: Cells turn the food we eat into energy . This process happens in the mitochondria, the cell’s powerhouses.

4. WHT IS ATP? ATP stands for Adenosine Triphosphate. ATP is the main molecule cells use to store and transfer energy Think of it as a tiny energy packet that powers everything in our bodies . Importance of ATP? ATP is like a battery for our cells. It gives us the energy to do things like run, jump, and even think! Without ATP, our bodies wouldn't work properly .

5. HOW ATP WORK : ATP is made up of three parts Adenosine and three phosphte groups When one phosphate group is broken off, energy is released . This energy powers many cellular processes. Where Does ATP Come From? Our bodies make ATP through a process called cellular respiration . During cellular respiration, our cells use oxygen to break down food molecules and make ATP . So , eating healthy food and breathing in oxygen helps our bodies make ATP !

6. How Our Bodies Use ATP? ATP is used for everything our bodies do, from moving muscles to thinking . Every time we move or do something, ATP is used up . Our bodies constantly make new ATP to keep up with our energy needs. Summary ATP is a molecule that gives us energy . Our bodies make ATP through cellular respiration . We use ATP for everything we do, and our bodies can recycle it to use again.

7. Energy in Animals: Animals eat food to get energy. The food is broken down into smaller molecules that cells can use. Energy in Plants: Plants make their own food using sunlight. They store energy in the form of sugars. Energy Flow in Ecosystems: Energy flows from the sun to plants to animals. This flow of energy supports all life on Earth. Metabolism: Metabolism is all the chemical reactions in our bodies that keep us alive. It includes breaking down food for energy and building new molecules.

8. Anabolic and Catabolic Reactions : Anabolic reactions build up molecules and require energy . Catabolic reactions break down molecules and release energy . Importance of Bioenergetics in Health: Proper energy balance keeps us healthy . Too much or too little energy can lead to health problems Summary: Bioenergetics studies how living things get and use energy . Energy is essential for life and comes from food and sunlight . Understanding bioenergetics helps us stay healthy and understand the world.

9. Biomagnetism

10. What is Biomagnetism ? Biomagnetism is the study of magnetic fields produced by living organisms . These fields are created by the electrical activity in the body, like in the heart and brain . History : Ancient Greeks first noted magnetic properties in living things . Modern biomagnetism began in the 1960s with the discovery of the human body's weak magnetic fields . Our bodies produce tiny magnetic fields due to electrical signals in cells . These fields are very small but can be measured with special tools .

11. Types of Biomagnetism : Magnetoencephalography (MEG ) Measures magnetic fields from brain activity . How MEG Works: Sensors called SQUIDs detect tiny magnetic fields in the brain. MEG creates a map showing brain activity. MEG helps us understand brain functions like thinking and feeling. It uses sensors to detect the brain's magnetic fields

12. Magnetocardiography (MCG) .MCG helps us see how well the heart is working. It uses sensors to measure the heart's magnetic fields. How MCG Works : MCG uses sensors to pick up magnetic signals from the heart . This helps doctors check for heart problems .

13. Applications of Biomagnetism in Medicine: Diagnosis : Detects brain disorders like epilepsy and heart diseases . Biomagnetic therapy uses magnetic fields to treat pain and speed up healing . Biomagnetism in Nature: Animals like birds and turtles use Earth’s magnetic field to navigate . Some bacteria produce magnetic particles to help them move

14. Research and Advances technique: Scientists are developing better MEG and MCG machines. New studies explore how magnetic fields can improve health treatments. Tools and Techniques: SQUIDs: Superconducting sensors that detect tiny magnetic fields. MRI (Magnetic Resonance Imaging): Uses strong magnetic fields to create images of the body.

15. Challenges in Biomagnetism : Measuring very weak magnetic fields is difficult . External magnetic noise can interfere with measurements . Summary: Biomagnetism studies magnetic fields from living organisms . It helps in medical diagnosis and treatment . Understanding biomagnetism can improve health and scientific knowledge.
