![]() ![]() What does catalase do? Under which conditions does it work best? Why do we need catalase in our liver? In this science fair project, you will use fresh (or frozen) liver as a source of catalase and investigate how the activity of the enzyme can change under certain conditions. When blended liver is exposed to hydrogen peroxide, the catalase enzyme in the liver reacts with the hydrogen peroxide to form oxygen gas, which creates the visible bubbles in this photograph, and water. When this chemical reaction occurs, you can see the oxygen gas bubbles escaping and causing the reaction to foam, as shown in Figure 1 below.įigure 1. One source of enzymes is the liver, which needs to break down many substances in the body.Ĭatalase is one enzyme from liver that breaks down harmful hydrogen peroxide into oxygen gas and water. A damaged enzyme will no longer work to catalyze a chemical reaction. Some enzymes can be damaged under certain conditions, such as heat. In other words, different tissues are home to different enzymes, and an enzyme should be able to function in the conditions that surround it in the tissue it's supposed to function in. They can be very fussy, and sometimes need to be in certain environments or conditions to work, and the ideal conditions are usually reflective of where the enzyme must normally function in the body. In other words, each enzyme has a particular type of reaction that it can activate.Įnzymes are proteins, which are molecules that are very large and dynamic. Certain catalysts work for certain kinds of reactions. A catalyst provides the necessary environment for the chemical reaction to occur, which speeds up the reaction. Made out of protein and they speed up the rate of a chemical reaction by acting as a catalyst. ![]() ![]() These types of chemical reactions can be helped to occur more quickly by using enzymes. Other chemical reactions need energy to happen, and without energy proceed very slowly or not at all. These reactions are usually very fast and spontaneous,Īnd give off energy. Sometimes chemical reactions happen by themselves. A chemical reaction is when chemicals come together and their molecules interact to form new chemicals. ![]()

![]() All in all, it seems like Upgrade Rare will be much better to use early on in the gearing process on items with several good options (e.g. Upgrade Rare seems a little bit more efficient if you have very common items (like Yang's Recurve), and a lot worse for very uncommon items (like Kridershot), while Reforge Legendary always has the same chance to yield the item you seek. I tried to approximate how many hours of game time you would need to invest to (given the numbers you could reach in high-end parties), and interestingly they turned out to be fairly even. You can farm up most of the materials passively when playing the game, and fortunately they don't overlap - Upgrade Rare requires 25 Death's Breath + 50 white / blue / yellow crafting materials, Reforge Legendary requires 5 of each bounty material and 50 Forgotten Souls. TL DW: Both recipes are okay to use if you really need that one specific item, most importantly build-defining pieces like an ancient weapon. ![]() ![]() Out of those 400 legendary bows, I got 57 Yang's Recurves (14.25%, 7x ancient), and it took 10000 Death's Breath + 20000 whites/blues/yellows (and another 6000 of each for crafting the yellow bows, but that's unnecessary to do on live when you can just collect them). Fortunately, you can craft both the yellow items for upgrading and the blue items to transform the materials in case you have too few of those (for the level 70 yellow version, you need 15 whites/blue/yellows, for the lvl 1 blue belt you need 2 whites/blues). I crafted 400 yellows bows and upgraded them to legendaries via the Cube, with the goal of getting a good ancient Yang's Recurve. In this video, I you can see what the process of Upgrading Yellows to legendaries looks like and how it compares to the Reforge Legendary recipe, backed up with some math to outline the advantages and disadvantages of both. I was trying out the Kanai's Cube a little bit on the PTR, and I decided to show my results and explain the two different paths of item progression that open up with it in patch 2.3. ![]() I've shared this video on my Youtube already a couple of days ago, and from the feedback I've heard I thought it might be a good idea to share it here as well.
