Question
1. (3pts) The location of cellular respiration is different in bacterial and eukaryotic cells. Where would each of the following factors or events of cellular respiration reside or occur in these different cells? Location options- cytoplasm, plasma membrane, outer mitochondrial membrane (OMM), inner mitochondrial membrane (IMM), matrix, intermembrane space, outside of the cell Event or factor Coenzyme A Nuclcotide phosphorylation Coenzyme Q Accumulation of a high Location in bacterial cell Location in eukaryotic cells proton concentration Conversion of pyruvate into lactate Succinate dehydrogenase ATP synthase Malate dehydrogenase Respirasomes (Ipt) What is the net change in standard free energy for phosphorylation of glucose to glucose-6-phosphate by hydrolysis of phosphocreatine? You will need to use the standard 2. free energy change for hydrolysis of phosphorylated compounds in Table 9.I, 3. (Ipt) Can phosphocreatine exergonically phosphorylate glucose-6-phosphate in the cell? Yes or no?Explanation / Answer
Coenzyme Q
Malate dehydrogenase
2) Phosphocreatine + H2O = creatine +Pi G = -43 Kj/mol
Glucose + Pi = Glucose-6- phosphate + H2O G = +13.8 Kj/mol
The net free energy change when the phosphorylation of glucose is copouled with dephosphorylation of phosphocretine is -29.2 kj/mol resulting in an exergonic reaction.
3) Yes phosphocreatinine can exergonically phosphorylate Gulucose-6-phosphate.
