Homology is often discussed in contrast to analogy. Not every similarity between two organisms is the result of common evolutionary ancestry. If two species find themselves in an environment conducive to some particular adaptation, this adaptation may emerge independently in both species. For example,...
What are the coenzymes in energy metabolism? What is phosphorylation? What is oxidative phosphorylation? What causes metabolic alkalosis? What are the biochemical pathways for catabolism and anabolism? What muscle fiber types uses oxidative metabolism?
What isNADP+in biology? Photosynthesis: Photosynthesis is a biological process that helps transfer energy from the sun into chemical energy. Plants and other photosynthetic organisms can convert energy into sugar, which can be utilized to make cellular energy. In photosynthesis, carbon dioxide is buil...
Regulatory Phosphorylation of Bacterial-Type PEP Carboxylase by the Ca2+-Dependent Protein Kinase RcCDPK1 in Developing Castor Oil Seeds. Phosphoenolpyruvate carboxylase (PEPC) is a tightly controlled cytosolic enzyme situated at a crucial branch point of central plant metabolism. In developi... S Yin...

PDK in turn blocks pyruvate conversion to acetyl-CoA in the mitochondria, thereby decreasing oxidative phosphorylation (OXPHOS)-mediated ROS production. Under normoxic conditions (sky blue color; right side of the diagram), UCP1 can generate heat in the process of electron transport chain-mediated ...
Oxidative Phosphorylation History Peter Mitchell proposed chemiosmotic hypothesis: energy from e - transport is stored in a proton gradient which is then used to make ATP Experimental support: 1. Uncouplers: dinitrophenol carries H + across membrane, dissipating the H + gradient DNP-treated mito endle...

What is the role of ATP in coupling the cells in anabolic and catabolic processes? By which type of phosphorylation, ATP is produced during fermentation? What is the role of dehydrogenase enzymes during respiration? What is ATP in biology?
Why is ATP important to cells? What is the structure of ATP? Where is ATP stored? Is phosphorylation endergonic or exergonic? The synthesis of ATP from ADP and P: A) Stores energy in a way that can boost cellular work. B) Transfer a phosphate and train the protein to perform work...
