How does phosphorylation work in regulating proteins? Phosphorylation regulates protein function andcell signaling by causing conformational changes in the phosphorylated protein. ... First, conformational changes regulate the catalytic activity of the protein. Thus, a protein can be either activated or in...
a. Compare the processes of substrate-level phosphorylation, oxidative phosphorylation and photophosphorylation to make ATP. b. How are they different? Similar? c. Where does the energy come from for each? In each case, describe the energy transfer proces ...
In which part of the citric acid cycle does substrate level phosphorylation occur? Explain what happens in the citric acid cycle and list four different products of the citric acid cycle. Which process makes takes NADH and makes NAD+? (A) Citric acid cycle (B) Electron transport ...
Compared to the generation of ATP by oxidative phosphorylation, what is a major difference in mechanism of ATP generation by substrate-level phosphorylation in glycolysis? A. A proton gradient is not involved B. The ATP produced has less energy content Compared to the generation...
Concept that describes the flexible transmission of forces generated by the flow of actin filaments to adhesion sites, allowing cells to exert a spatially and temporally regulated grip on the substrate. It has a crucial role in the mechanical connection between the actin flow and cell adhesion comp...
In both cases, substrate rec- ognition by Grrlp requires phosphorylation of residues within the Cln2p and Gic2p degrons. Because these residues in the Cln2p and Gic2p degrons are differentially phosphorylated, the two target proteins are destroyed in different ways: Cln2p is continuously ...
Hsp90 is an essential molecular chaperone responsible for the folding and activation of hundreds of ‘client’ proteins, including the glucocorticoid receptor (GR). Previously, we revealed that Hsp70 and Hsp90 remodel the conformation of GR to regulate l

What process requires oxygen to function? a. Aerobic respiration b. Anaerobic respiration c. Alcoholic fermentation d. Lactate fermentation e. Substrate-level phosphorylation If no oxygen was present, could a yeast cell make ATP by metabolizing glucose? If so, what process would the yeast ...
1. Where is the electron transport chain located? 2. Where does the most substrate-level phosphorylation occur? 3. What membrane do protons cross in the synthesis of ATP? Explain how ATP is produced in the inner mitochondrial membrane with the help of the respiratory chain. ...
