Regulation of glycogen breakdown
WebApr 8, 2024 · Glycogen is the preferred storage form of glucose in animals. This is because glycogen is more compact and soluble than glucose, allowing for efficient storage and rapid release when needed. Additionally, glycogen is less osmotically active than glucose, ... WebSummary. (1). The capacity of cold-adapted and non-adapted rats to increase heat production by non-shivering regulatory means was tested. In both groups, muscular activity was blocked by curare. Only cold-adapted animals could increase heat production sufficiently to maintain body temperature as the test room was cooled.
