Today we are going to talk about an incredible process that uses light and gas to do something Amazing that we all love —- sugar! Unfortunately, we cannot do this amazing, incredible process — which is known as photosynthesis. Some types of protists can do photosynthesis. Some types of bacteria can. And of course the plants know. Plants will focus on this video clip.
Animals and amoebas simply escaped to this ability. But we benefit from that because this process also produces oxygen — the very gas we need to breathe. So this process is important to us to understand the small background. Plants and animals need sugar. Specifically, glucose. Plants, like animals, use glucose to produce ATP energy in a process known as cellular respiration. ATP energy is crucial for cells to carry out their cellular activities. But while we have to look for food this glucose, plants instead can do photosynthesis to make their own.
So that's nice, because they don't have to go anywhere to understand it. Plants have an adaptation to create them able to perform photosynthesis in different varieties of environment. Here is the formula for photosynthesis. To the left of the formula you will find the reactants. This means that these are inputs. The plant must have these to do this by photosynthesis. To the right of the formula, find products. That is, those are the items that the plant produces. Outputs. Sometimes the formula is written a little differently. Technically it needs it be balanced and sometimes the light above is written on the arrow to show that it is in it the presence of light can look like this. The product C6H12O6 is sugar, specifically, glucose.
Photosynthesis is not just a formula. Have you ever tried to catch light? It is difficult. Plants have light-capturing molecules, pigments that help them. See, visible light, has different wavelengths. Different wavelengths of light vary colors. If you've ever played a prism before, you might have been able to see how light can be staggered into rainbow colors due to these different wavelengths. One pigment which plants use chlorophyll for photosynthesis. Chlorophyll is an expert in absorption red and blue light, but not so green light. Because it doesn't absorb too much green light reflecting green light. Therefore, many plants look green in our eyes. Push There are more pigments in addition to chlorophyll that work with different light wavelengths and This may explain why green is not the only color you see in plants. Chlorophyll is a pigment found in chloroplasts of plant cells. This amazing organelle was not found in animal cells. There are two main reactions that occur in chloroplast, create photosynthesis. It depends on the light reaction and the light independent reaction.
It is also called a light-independent reaction Calvin cycle or even … a dark reaction. A light-dependent reaction occurs with tylacoids. What are tylacoids? Well … they're scarce separation in chloroplast and contain pigment. They tend to be nicely stacked. We call it a collective container as granum. The best way to describe a granu is that Looks like … a stack of green pancakes. Yes. Very, very small green pancakes. IN light dependent reaction, light is transferred — means a complex process that involves more "Photosystems" – into chemical energy. By chemical energy we mean ATP (we mentioned that before — that's energy!) and NADPH.
We'll get to it later. During the light Dependent reaction, the water (which is necessary for this process to work) is "split". That is, if you think of a chemical formula for water that is H 2 O — it is broken down that way you get electrons, protons and oxygen. Thus, oxygen is also the product of this reaction. So let's look at our formula. Light and water on the reaction side this light-dependent reaction. And oxygen was also produced from this dependent light reaction. What about other items in the formula? And why do this ATP and NADPH? What they do? Well … that's the next step —- a light-independent reaction. The light independent reaction – also occurs in chloroplast. The name is misleading. It it will not happen in the dark. It needs items from a light dependent reaction so that happen simultaneously. While it happened in chloroplast – we'll never get out of it chloroplast with this, does not happen in tylacoids. Instead, it happens tree. The tree is liquid outside the tylacoid.
The reaction is carbon dioxide must be repaired. What do I mean to fix? Nothing was wrong with that. Firmly, I mean, with the additional help of the main enzyme, inorganic carbon dioxide changes more usable organic form. The ATP of the light-dependent reaction helps to supply energy. NADPH from a light-dependent reaction that reduces performance —- I mean that helps to add high energy electrons to this process. So in a very complex series pathways, solid carbon dioxide, ATP, and NADPH are used to produce this product finally, it can be converted to glucose. Let's look at this formula. Last time, I promise. So here we have a ring from a light-dependent reaction. Now, note the other items —- CO2 on the reactant and glucose on the product side – you they were from light-independent reactions.
Together dependent on light and cycle an illuminated independent cycle — which happens simultaneously — produces the glucose that plants need to survive. This The process of photosynthesis is an essential plant for sugar production. Photosynthesis too it supplies organisms with the oxygen they need because you remember that oxygen was also a product. And because plants are producers of food network, photosynthesis is important because plants supply energy to many hungry consumers.
