解糖とは?
解糖とは?
Overview Cells make energy by breaking down macromolecules. Cellular respiration is the biochemical process that converts "food energy" (from the ...
解糖のエネルギーが必要な段階
解糖のエネルギーが必要な段階
Glucose is the source of nearly all energy used by organisms. The first step of converting glucose into usable energy is called glycolysis. Glycolysis ...
解糖のエネルギー放出段階
解糖のエネルギー放出段階
Glycolysis is divided into two phases based on whether energy is utilized or released. While the first phase consumes ATP, the second phase produces ...
ピルビン酸酸化
ピルビン酸酸化
After glycolysis, the charged pyruvate molecules enter the mitochondria via active transport and undergo three enzymatic reactions. These reactions ensure ...
クエン酸回路
クエン酸回路
The citric acid cycle, also known as the Krebs cycle or TCA cycle, consists of several energy-generating reactions that yield one ATP molecule, three NADH ...
電子伝達系
電子伝達系
The final stage of cellular respiration is oxidative phosphorylation that consists of two steps: the electron transport chain and chemiosmosis. The ...
化学浸透
化学浸透
Oxidative phosphorylation is a highly efficient process that generates large amounts of adenosine triphosphate (ATP), the basic unit of energy that drives ...
電子キャリア
電子キャリア
Electron carriers can be thought of as electron shuttles. These compounds can easily accept electrons (i.e., be reduced) or lose them (i.e., be oxidized). ...
発酵
発酵
Most eukaryotic organisms require oxygen to survive and function adequately. Such organisms produce large amounts of energy during aerobic respiration by ...
食事のつながり
食事のつながり
In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as ...
細胞呼吸とは?
細胞呼吸とは?
Organisms harvest energy from food, but this energy cannot be directly used by cells. Cells convert the energy stored in nutrients into a more usable ...
クエン酸回路の生成物
クエン酸回路の生成物
The cells of most organisms—including plants and animals—obtain usable energy through aerobic respiration, the oxygen-requiring version of ...
解糖の成果
解糖の成果
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler ...
ATP収量
ATP収量
Cellular respiration produces 30 - 32 ATP per glucose molecule. Although most of the ATP results from oxidative phosphorylation and the electron transport ...
