Enzymes are proteins, and proteins are basically a large chain of amino acids (polymer). So imagine when the chain is clumped into a 3D thing (see picture), it is slightly elastic (since there are spaces) and can have a bit of movement for the substrate to fit in. However, the shape is specific as it will return back to its original position once the substrate has left. Just imagine a silicone cup, when you stretch it a bit to fit a slightly larger ball in, it expands a little. When u remove the ball, it returns to its original shape. Similarly, the enzyme active site will return to its original shape but can be slightly molded for a short while, and that is what the sentence meant. It’s quite hard to explain without an actual model/ video, so if you don’t understand you can comment below!
Correct answer choice is:
D) Elements continuously cycle between the physical environment and living organisms.
Explanation:
Any nonliving matter that living things want is termed a nutrient. Carbon and nitrogen are parts of nutrients. Unlike energy, the object is converted into ecosystems. Decomposers deliver nutrients when they cut down dead organisms. When one organism eats a different organism, it takes all of its nutrients. Nutrients can also cycle out of an ecosystem. Falling leaves may be moved out of an ecosystem by a water. Decomposers cut down dead organisms into nutrients and carbon dioxide, which they respire into the air.
So we all know that the Earth rotates around the Solar system all the time nonstop. But wait there is more. One half of the Earth which is North America and South America are faced to the sun so you can tell that we are in summer. While we are in summer,the other half of the Earth which is Europe,Africa,Asia and Austrialia ( I think I spelled that wrong who cares about that) they are in winter. This process continues nonstop there is no break.
