Phosphorylation isthe uptake of a phosphorous molecule by an ATP molecule to power.chemical reactions. ... Phosphorylation is the breakdown of a pyrophosphate molecule which gives phosphate ions. Where does pro
What is oxidative phosphorylation and how does it affect cell metabolism? How does the cell make ATP from the electron transport chain? Briefly describe the mechanism. What biological processes occur in a cell's mitochondria? How does the presence of succinate an...
Does phosphorylation activate or deactivate? The phosphorylation of a proteincan make it active or inactive. Phosphorylation can either activate a protein (orange) or inactivate it (green). Kinase is an enzyme that phosphorylates proteins. Phosphatase is an enzyme that dephosphorylates proteins, effecti...
the reactions occur within themitochondria. Oxidative phosphorylation consists of the reactions ofthe electron transport chainand chemiosmosis. In summary, the redox reaction passes electrons from proteins and other molecules along the electron transport chain in the inner membrane of the mitochondria...
Fill in the blank. Organisms can synthesize ATP by oxidative phosphorylation when they ___. Explain how phosphofructokinase (PFK) can both use ATP and be inhibited by it. Energy transfers occur in all cellular activities. Explain this process and the role of...
The question is: does the dynamic association of these complexes act as a signaling mechanism to trigger mitochondrial biogenesis? During germination, the activation of mitochondrial gene expression appears to occur very early (Law et al. 2012). This raises the question, what role does organellar ...
Light reactions are part of the photosynthesis process that takes place in the thylakoids, while dark reactions, also known as biochemical, light-independent, or Blackman’s reactions, occur in the stroma of the chloroplasts. Also referred to as photochemical and Hill reactions, the light reaction...
(PLB). When dark-grown plants are exposed to light, a series of physiological and biochemical changes occur. This transition, called de-etiolation or simply as greening, is coupled to a light-driven etioplast-to-chloroplast transition and chlorophyll biosynthesis (Kanervo et al.2008; Armarego-...
occur. It is therefore critical to perform PET staging before commencement of anti-tumour therapy. Integration of CT data Integrating the anatomic information provided by CT is important for accurate PET/CT interpretation as it may increase the specificity and sensitivity of PET findings. Detailed ...
How does NAD+ become NADH? Why does this electron transfer (NAD+ to NADH) occur? How does chemiosmosis relate to oxidative phosphorylation? Explain glycolysis and how glucose is broken down into two molecules of pyruvate. How much NADH is produced during oxidative metabolism?
