To determine:
The reason that why oxidative photosynthetic carbon cycle
Introduction:
Photorespiration is the process in which the plants take up the oxygen from the environment and produces carbon dioxide to the environment. Photorespiration process involves three different organelles of plant cells: chloroplast, peroxisome and mitochondria. The end product of the photorespiration is formation of carbon dioxide.
To determine:
The location of photorespiration and mitochondrial respiration occur in cells and under what circumstances is to be determined.
Introduction:
Photorespiration is the process in which the plants take up the oxygen from the environment and produces carbon dioxide to the environment. The end product of photorespiration is the production of carbon dioxide.
To determine:
The path of electron flow in photosynthesis respiration and mitochondrial respiration is to be determined.
Introduction:
Photorespiration is the process in which the plants take up the oxygen from the environment and produces carbon dioxide to the environment. Photorespiration process occurs during day time while mitochondrial respiration occurs during day and night time.

- fill in the table and circle the active sitearrow_forwardThe two half reactions for beginning and end of the electron transport chain are given below in standard form. Calculate & for the overall process. Using the Nernst equation (AG° = -n Fo, F= 96.485 kJ/volt mol), calculate AG°. Explain the need for a stepwise process in the electron transport chain. NAD* + H+ + 2 e- = NADH ½ 0г + 2H+ + 2е- = H20 = -0.32v E = +0.82Varrow_forwardanswer the questions and the example steps should be from carbohydrates glycolysis and citric acid cycle. Please put down reactions and structuresarrow_forward

- Please draw out the molecular structures of each molecule and show how each enzyme + cofactor would affect the following molecule in the human metabolic pathway. (This is a metabolic map)arrow_forwardPlease draw out the molecular structures of each molecule and show how an enzyme + cofactor would affect the following molecule in the human metabolic pathway to create energy.arrow_forwardPlease draw out the molecular structures of each molecule and show how each enzyme + cofactor would affect the following molecule in the human metabolic pathway.arrow_forward
- Please draw out the mechanism with curved arrows showing electron flow. Pyruvate is accepted into the TCA cycle by a “feeder” reaction using the pyruvate dehydrogenase complex, resulting in acetyl-CoA and CO2. Provide the mechanism for this reaction utilizing the TPP cofactor. Include the roles of all cofactors.arrow_forwardPyruvate is accepted into the TCA cycle by a “feeder” reaction using the pyruvate dehydrogenase complex, resulting in acetyl-CoA and CO2. Provide the mechanism for this reaction utilizing the TPP cofactor. Include the roles of all cofactors.arrow_forwardThe mitochondrial ATP synthase has 10 copies of the F0 subunit “c”, and the [H ] in the mitochondrial inner membrane space (IMS) is 6.31 x 10-8 M and the [H + ] in the matrix is 3.16 x 10-9 M. Calculate the minimum membrane potential (∆Ψ) necessary to make ATP synthesis thermodynamically favorable. [Assume ∆G' ofphosphate hydrolysis of ATP is - 45 kJ/mol.]arrow_forward
