Open Access research shaping international environmental governance...

Strathprints makes available scholarly Open Access content exploring environmental law and governance, in particular the work of the Strathclyde Centre for Environmental Law & Governance (SCELG) based within the School of Law.

SCELG aims to improve understanding of the trends, challenges and potential solutions across different interconnected areas of environmental law, including capacity-building for sustainable management of biodiversity, oceans, lands and freshwater, as well as for the fight against climate change. The intersection of international, regional, national and local levels of environmental governance, including the customary laws of indigenous peoples and local communities, and legal developments by private actors, is also a signifcant research specialism.

Abstract

The diversity of mitochondrial arrangements, which arise from the organelle being static or moving, or fusing and dividing in a dynamically reshaping network, is only beginning to be appreciated. While significant progress has been made in understanding the proteins that reorganise mitochondria, the physiological significance of the various arrangements is poorly understood. The lack of understanding may occur partly because mitochondrial morphology is studied most often in cultured cells. The simple anatomy of cultured cells presents an attractive model for visualizing mitochondrial behaviour but contrasts with the complexity of native cells in which elaborate mitochondrial movements and morphologies may not occur. Mitochondrial changes may take place in native cells (in response to stress and proliferation), but over a slow time-course and the cellular function contributed is unclear. To determine the role mitochondrial arrangements play in cell function, a crucial first step is characterisation of the interactions among mitochondrial components. Three aspects of mitochondrial behaviour are described in this review: (1) morphology, (2) motion and (3) rapid shape changes. The proposed physiological roles to which various mitochondrial arrangements contribute and difficulties in interpreting some of the physiological conclusions are also outlined.
