Why are enzymes important for cellular respiration

What will we discover today? Cells need to have ATP because it’s the gasoline that powers all living things. And by laundromat, I mean your body! Cellular respiration is like a change machine: you’re turning sugars into ATP so it will be a usable form of energy. If you go to a coin operated laundromat, they all seem to run why are enzymes important for cellular respiration quarters for some reason.

10 bill into the change machine and you get 40 quarters and now you could use the coin operated washers and dryers. 10 bill will give you 40 quarters. 100 bill because it has that much more energy. If you don’t have major enzymes involved in chemical digestion, you can’t make ATP and you’re going to die. Even if I brought in all the food in the world and then I diabolically suck all the oxygen out of this room, you’re still going to die. You need oxygen to unlock the energy that’s in the food.

Cellular respiration also explains why we are breathing oxygen and why we exhale carbon dioxide. In essence, the energy that was in covalent bonds of the glucose molecule is being released. In actuality, this process requires several steps because the sugar is enzymes that catalyze the transfer of electrons are called down by baby steps, little by little, and is catalyzed many enzymes and coenzymes. Nothing is perfectly efficient in this world. The nutritional Calorie is 1000 standard calories. A kcal is a kilocalorie which is 1000 calories.

So a nutritional Calorie is the same as a kcal. It’s impossible to convert one form of energy into another without creating heat. This release of heat is predicted by the law of thermodynamics. If you start to exercise, cellular respiration starts to speed up inside your muscle cells to produce more ATP, so your body starts breaking down sugars at a faster rate, you breathe oxygen at a faster rate and exhale carbon dioxide at a faster rate and give off a lot more heat at the same time. What living things do is they take oxygen and transfer the hydrogens that come off of sugar molecules and stick them onto oxygen. When you attach a couple hydrogens onto an oxygen, you get water. For this reason, it is said that oxygen is a hydrogen acceptor. Oxidation: The glucose is being oxidized into carbon dioxide.
