 * 1) **What is the relationship between energy and matter?**
 * 1) **How is energy significant to biological system?
 * 1) **Can an organism survive without the exchange of matter with its environment?**
 * 1) **Are all matters living and all living organisms made of matter?**
 * 1) **Can living organisms create and destroy energy?**
 * 1) **Can living organisms create and destroy matter?**

> Change in the form of any matter involves energy. ** > Changes in the organisms are dependent on its environment. > Living organisms require energy to carry out life processes (e.g. respiration) > Energy flows in biological processes obeys the laws of thermodynamics. > **Everything needs energy.**
 * Facts

Anabolism: Photosynthesis Catabolism: Respiration

It gives energy to perform life processes.
 * Why do we need to respire?

****Do the structure and organism of the living system change when energy is released from them?** The energy is transformed from one to another.


 * How are the respiratory systems of animals organized efficiently to carry out its functions?

Can there be any metabolism without enzymes? No. Enzymes are used to speed up reaction by activation energy. Enzymes lower the activation energy of the matter, hence speeding up the reaction: less energy is needed for the same process to take place.

1. Living organisms release energy within the biological molecule into forms they can use to carry out life processes. 2. Process of the release of energy is affected by the external environment. 3. The structure and organization of the respiratory system is dictated by the function that it serves. 4. Metabolic pathway is a sequence of enzyme-controlled reactions. ** **
