many gases like nitrogen‚ oxygen‚ carbon dioxide and water vapour. All living beings need oxygen to break down glucose molecules and get energy for their activities. This results in the production of carbon dioxide. Another process which results in the consumption of oxygen and the concomitant production of carbon dioxide is combustion. This includes not just human activities‚ which burn fuels to get energy‚ but also forest fires. Despite this‚ the percentage of carbon dioxide in our atmosphere is a

six 5-carbon molecules to form twelve 3-carbon molecules. Next‚ these are converted into higher energy forms using ATP and high energy electrons from NADPH. Lastly‚ two of the twelve 3-carbon molecules are removed from the cycle‚ used by the plant for metabolism and growth; the remaining ten are converted back into six 5-carbon molecules‚ which ultimately begin the next cycle. The Calvin Cycle has three in depth parts: C02 fixation‚ C02 reduction‚ and RuBP regeneration. During C02 fixation‚ C02

GPS: S7L4 – Students will examine the dependence of organisms on one another and their environments. Chapter 19 Cycles in Our Ecosystems Anything that has mass and occupies space is matter. This matter must be used over and over again in our closed ecosystem‚ we call this recycling. We will discuss a few of the very important cycles life depends on. The Water Cycle The movement of water among the oceans and our atmosphere‚ and the movement of fresh water (lakes‚ rivers‚ and streams)

Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor
