What is difference between ATP synthesis in mitochondria and chloroplast?
What is difference between ATP synthesis in mitochondria and chloroplast?
Mitochondria and chloroplast are organelles found in a plant cell. However, chloroplast is absent in an animal but mitochondria is found in both. Mitochondria generates energy for the cell in the form of ATP using oxygen and nutrients. Chloroplast is the site for photosynthesis in a plant cell.
How is the synthesis of ATP in the mitochondria similar to the synthesis of ATP in the chloroplast?
How is the synthesis of ATP in the electron transport chain of mitochondria similar to the synthesis of ATP in chloroplasts? they both have the ATP synth-ace. both use NADH+ electrons etc. the similarity is that they both have electrons that are transfered.
What is the major difference between mitochondria and chloroplasts?
Mitochondria are the “powerhouses” of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They’re responsible for capturing light energy to make sugars in photosynthesis.
What is the difference between an ATP synthase molecule in a chloroplast and an ATP synthase molecule in a mitochondria?
In chloroplasts, ATP synthase receives protons from thylakoid lumen, which volume is small as compared to the mitochondrial intermembrane space (IMS) and which pH value can drop to the values below 5 (Oja et al., 1999), while in the mitochondrial IMS it drops only slightly below 7 (Moore and Rich, 1985; Porcelli et al. …
Do chloroplasts and mitochondria make ATP?
In plant cells, chloroplasts convert light energy into chemical energy, and mitochondria consume the chemical energy to produce ATP.
What is the process of generating ATP in mitochondria and chloroplasts called and what are the main differences between the process in each of these organelles?
The process of ETC in chloroplasts uses phosphorylation (oxidation of water to give oxygen and NADP), and electrons are accepted. Whereas in mitochondria, the process used is oxidative phosphorylation (NAD and FAD donate electrons to reduce oxygen and produce water).
What is the process of generating ATP in mitochondria and chloroplasts called?
The common pathway used by mitochondria, chloroplasts, and procaryotes to harness energy for biological purposes operates by a process known as chemiosmotic coupling—reflecting a link between the chemical bond-forming reactions that generate ATP (“chemi”) and membrane-transport processes (“osmotic”).
Does chloroplast produce ATP?
Chloroplasts and mitochondria are the major ATP producing organelles in plant leaves.
Where does the energy that drives ATP synthesis in the mitochondria and chloroplast come from?
Chapter 14Energy Conversion: Mitochondria and Chloroplasts. Through a set of reactions that occur in the cytosol, energy derived from the partial oxidation of energy-rich carbohydrate molecules is used to form ATP, the chemical energy currency of cells (discussed in Chapter 2).
Where do chloroplasts make ATP?
All electron-transport processes occur in the thylakoid membrane: to make ATP, H+ is pumped into the thylakoid space, and a backflow of H+ through an ATP synthase then produces the ATP in the chloroplast stroma.
What is the process of generating ATP in chloroplasts called?
The process of ETC in chloroplasts uses phosphorylation (oxidation of water to give oxygen and NADP), and electrons are accepted. The electron transport chain in chloroplasts utilizes energy from the sun to drive the process.
How is ATP synthesized in the chloroplast?
During photosynthesis in plants, ATP is synthesized by ATP synthase using a proton gradient created in the thylakoid lumen through the thylakoid membrane and into the chloroplast stroma. An F-ATPase consists of two main subunits, FO and F1, which has a rotational motor mechanism allowing for ATP production.
What is the difference between etetc in mitochondria and chloroplasts?
ETC in mitochondria takes place in the cristae of mitochondria. ETC in chloroplasts takes place in the thylakoid membrane of the chloroplast. NAD and FAD involve in ETC of mitochondria. NADP involves in ETC of chloroplasts. Proton gradient acts from the intermembrane space up to the matrix during the ETC of mitochondria.
How do the mitochondria and chloroplasts start the chemical reactions?
The mitochondria starts the chemical reactions by glycolysis using 2 pre-existing ATP. Chloroplasts start the process by turning light into ATP. I have notion that the same amount of electrons are used transferred in both that is just a notion
How is ATP synthesized in animal cells?
ATP is remarkable for its ability to enter into many coupled reactions. In animal systems, the ATP can be synthesized in the process of glycolysis in which there is a net production of two ATP molecules in a cycle. This glycolysis is a major step in anaerobic respiration.
What is the final electron acceptor of etc in mitochondria?
Oxygen is the final electron acceptor of ETC in mitochondria. Chlorophyll in cyclic photophosphorylation and NADPH+ in noncyclic photophosphorylation are the final electron acceptors in ETC in chloroplasts.
