Understanding ion transport by quantification of mitochondrial swelling. 通过量化线粒体肿胀了解离子转运。
Pub Date : 2000-01-01
Königsberg

Suspensions of mitochondria are turbid and scatter light. An increase in the matrix volume (swelling) due to the influx of permeable solutes results in a decrease in the amount of light scattered. This property can be used to study solute fluxes across the mitochondrial inner membrane. A rapid method for isolating mitochondria is presented along with three swelling experiments using energized and non-energized mitochondria to illustrate ion transport across energy transducing membranes.

线粒体悬浮液浑浊且散射光线。由于渗透性溶质的涌入,基质体积(膨胀)的增加导致光散射量的减少。这一性质可用于研究线粒体内膜的溶质通量。提出了一种快速分离线粒体的方法,以及三个使用带电和非带电线粒体的膨胀实验,以说明离子在能量转导膜上的运输。

The experiment described in this paper introduces students to the practical use of an enzyme (beta-galactosidase, or lactase) acting on a natural substrate. The enzyme is immobilized onto a cheap support, and the immobilized derivative is used in a packed-bed reactor for continuous milk lactose hydrolysis. The results are compared to those obtained for discontinuous batch reactors with soluble enzyme. A mathematical model of the two types of reactors is run, and its results are compared with the experimental data obtained.
