2_photosynthesis_respiration_essential_questions

Can you use your understanding of Macromolecules and Photosynthesis to answer these questions:


 * 1) What is the relationship between energy and matter?

Energy is the key to what all living things do and all organisms need energy to carry out the important survival processes. It is very significant to all living things and thus significant to the biological system. >
 * 1) How is energy significant to biological system?

No, organisms adapt to their environment and its changes will also affect the organism
 * 1) Can an organism survive without the exchange of matter with its environment?

Not all matter is living, but all living organisms are made of matter.
 * 1) Are all matters living and all living organisms made of matter?

No, energy can only be changed or converted.
 * 1) Can living organisms create and destroy energy?

Yes
 * 1) Can living organisms create and destroy matter?

 Topical Enduring Understanding


 * 1) Change in the form of any matter involves energy.
 * 2) Survival of the biological system depends on the conversion of energy from one form to another.
 * 3) Changes in the organism are dependent on its environment.
 * 4) Living organisms require matter and energy to maintain its complexity and organisaton.


 * 1) <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">Energy flow in biological processes obeys the laws of thermodynamics.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">If we narrow it further and focus only on the unit of RESPIRATION, you will be able to answer these questions at the end of the unit

<span style="font-family: Arial,Helvetica,sans-serif;">We need to exchange gases to obtain the oxygen needed by our body and to get rid of waste gas, carbon dioxide.
 * 1) <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">Why do we need to respire?

<span style="font-family: Arial,Helvetica,sans-serif;">Yes, each living system will have its own way of using energy for survival, for example photosynthesis in plants.
 * 1) <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">Do the structure and organisation of the living system change when energy is released from them?


 * 1) <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">How are respiratory systems of animals organised efficiently to carry out its functions?

>


 * 1) <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">Can there be any metabolism without enzymes?

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">You will be able to explain where the following enduring understanding of this unit is true:


 * 1) <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">Living organisms release energy within the biological molecule into forms they can use to carry out life processes.
 * 2) <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">Process of the release of energy is affected by external environment.
 * 3) <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">The structure and organisation of the respiratory system is dictated by the function that it serves.
 * 4) <span style="font-family: Arial,Helvetica,sans-serif; font-size: 12pt;">Metabolic pathway is a sequence of enzyme-controlled reactions.
