Describe the role of the citric acid cycle as a central metabolic mechanism. Explain what happens to the cells' abilities to oxidize acetyl CoA when intermediates of the cycle are drained off for amino acid biosynthesis. Describe the three steps in photosynthesis, detailing the interrelationships among them. (c.f. the discussion in the online classroom). For this assignment you don't need to use other sources besides the information given in the commentary, animations, and/or textbook. However, you may consult outside sources as necessary for completing this assignment. Please, always cite your sources: that includes citations from the commentary, the textbook, and the animations, as well as outside sources (if used). See APA Style for appropriate citation style.The last protein structure to mention is quaternary (4º). This type of structure refers to the arrangement of subunits and to the nature of the subunits interactions. To sum this up proteins that consist of more than one polypeptide chain will display quaternary structure. Each individual polypeptide chain in a protein is referred to as a subunit. A dimer is known to be the simplest sort of quaternary structure as it contains two identical subunits. Interactions between subunits of a protein containing a quaternary structure are usually weak interactions such as hydrogen bonding, ionic bonding, and van der Waals. It is important to note that quaternary structures can be simple such as two identical subunits or even complex where dozens of different polypeptide chains come together. In conclusion by understanding the four different protein structures it allows one to picture and better understand a proteins shape and how it interacts.
