2 paź 2020 · This animation shows how the enzyme complexes of the electron transport chain harvest energy from cofactor molecules to pump protons across the mitochondrial membrane and establish a chemical gradient.
2 mar 2014 · Each turn of the cycle produces ATP, NADH and FADH2 that are used in cellular respiration to produce more ATP for the cell. Acetyl CoA links glycolysis to the Krebs cycle by entering the cycle in the first step of condensing with oxaloacetate.
Essentially, the energy released from the ATP hydrolysis provides the energy required to power the pump and transport Na + and K + ions. ATP performs cellular work using this basic form of energy coupling through phosphorylation. The sodium-potassium pump is an example of ATP powering cellular work.
7 mar 2017 · The document discusses the tricarboxylic acid (TCA) cycle, also known as the Krebs cycle or citric acid cycle. It provides three key points: 1. The TCA cycle is the final common pathway for the oxidation of carbohydrates, fats, and proteins to produce energy in the form of ATP.
Mulple ways to show ATP. 3D model based on molecular structure. 2D model highlighng atoms (carbon, oxygen, nitrogen, phosphorus) Simplified 2D models. ATP holds energy in chemical bonds between its phosphate groups.
The reactions of cellular respiration can be grouped into three main stages and an intermediate stage: glycolysis, Transformation of pyruvate, the Krebs cycle (also called the citric acid cycle), and Oxidative Phosphorylation. Figure \(\PageIndex{3}\) gives an overview of these three stages, which are also described in detail below.
2 paź 2020 · ATP synthase uses the energy stored in the proton gradient to catalyze the synthesis of ATP. The molecular machinery involved in this process converts chemical energy to mechanical energy and provides a great example of the relationship between the structure and function of macromolecules.
