網頁The validity of a chemiosmotic hypothesis for uptake of weak acids as an explanation for the accumulation of auxin by cells has been explored further by comparing the uptake of indole-3-acetic acid (IAA) by 1-mm segments of corn (Zea mays L.) coleoptiles with that of benzoic acid and two neutral ind … 網頁According to the chemiosmotic hypothesis, ATP is produced by due to the proton gradient created across the mitochondrial membrane. The essential components required for … 網頁However, with time, scientific evidence began to prove the chemiosmotic hypothesis. The theory was accepted, and Mitchell was awarded Nobel Prize in Chemistry in 1978. The chemiosmotic theory now explains the … city of bellevue ne fire department

The word "matrix" … Peter D. Mitchell proposed the chemiosmotic hypothesis in 1961. In brief, the hypothesis was that most adenosine triphosphate (ATP) synthesis in respiring cells comes from the electrochemical gradient across the inner membranes of mitochondria by using the energy of NADH and FADH2 … 查看更多內容 Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient. An important example is the formation of adenosine triphosphate (ATP) by the … 查看更多內容 The complete breakdown of glucose releasing its energy is called cellular respiration.
