Abstract

MITOCHONDRIA IN PIGEON BREAST MUSCLE ARE COMPOSED OF TWO PROTEIN GELS

a fibrous gel, in the form of a folded ribbon, enclosed within a non-fibrous matrix. An external limiting "membrane" is not demonstrated, and there is poor demarcation between the mitochondria and adjacent structures or sarcoplasm. No internal structure has been determined for sarcosomes. These structures, however, are symplasmic with mitochondria and usually are located within mitochondrial depressions. They apparently have a high lipid content. The myofibrils also have no external limiting "membranes" and the mitochondria and sarcosomes are symplasmic with them. The mitochondria normally lie in the intermyofibrillar sarcoplasm oriented with their longitudinal axes parallel to the myofibrils. Cross-sections show that the myofilaments are oriented into well defined sheets.

摘要

家鸽胸肌中的线粒体由两种蛋白质凝胶组成

一种是纤维状凝胶,呈折叠带状,包裹在非纤维状基质中。未发现外部的限制“膜”,线粒体与相邻结构或肌浆之间的界限不清晰。肌粒的内部结构尚未确定。然而,这些结构与线粒体是共质体,通常位于线粒体凹陷内。它们显然含有高脂质含量。肌原纤维也没有外部的限制“膜”,线粒体和肌粒与它们是共质体。线粒体通常位于肌原纤维间的肌浆中,其纵轴与肌原纤维平行。横截面显示肌丝排列成界限分明的薄片。
