The chloroplast adenosine triphosphate (ATP) synthase is located in the thylakoid membrane and synthesizes ATP from adenosine diphosphate and inorganic phosphate at the expense of the electrochemical proton gradient formed by light-dependent electron flow.

Do mitochondria and chloroplasts have ATP synthase?
The bulk of ATP synthesis in plants is performed by ATP synthase, the main bioenergetics engine of cells, operating both in mitochondria and in chloroplasts.
How does ATP synthase work in chloroplasts?
The chloroplast ATP synthase catalyzes the light-driven synthesis of ATP and is activated in the light and inactivated in the dark by redox-modulation through the thioredoxin system. It has been proposed that this down-regulation is important for preventing wasteful hydrolysis of ATP in the dark.
Do chloroplasts use ATP energy?
Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
How is ATP produced in chloroplasts quizlet?
In chloroplasts, ATP is produced as a result of harvesting energy from light. In chloroplasts, the ATP is used in the fixation of CO2 into sugars. Membrane bound mechanisms – ATP synthase is found in the mitochondrial inner membrane, the chloroplast thylakoid membrane and the inner membrane of eubacteria.
What powers the ATP synthase enzymes in mitochondria and chloroplasts?
The synthesis of ATP requires an electrochemical proton gradient across the inner mitochondrial or thylakoid membrane that is driven by the transport of protons back into the matrix through the Fo domain. Chloroplast ATP synthase shows a complex regulation of its catalytic activity.
Where is ATP synthase in chloroplast?
The chloroplast adenosine triphosphate (ATP) synthase is located in the thylakoid membrane and synthesizes ATP from adenosine diphosphate and inorganic phosphate at the expense of the electrochemical proton gradient formed by light-dependent electron flow.
Do plants have ATP synthase?
The bulk of ATP synthesis in plants is performed by ATP synthase, the main bioenergetics engine of cells, operating both in mitochondria and in chloroplasts.
Is ATP synthase an enzyme?
ATP synthase is the very last enzyme in oxidative phosphorylation pathway that makes use of electrochemical energy to power ATP synthesis [7, 8, 9, 10]. ATP synthase is one of the most ubiquitous and plentiful protein on the earth, accountable for the reversible catalysis of ATP to ADP and Pi.
How do plants make ATP?
Plants, through the process of photosynthesis, make use of the sunlight to energise and generate glucose through the available water and carbon dioxide. This glucose through pathways can be converted into pyruvate. Through cellular respiration, pyruvate in turn gives ATP (adenosine triphosphate).
Why do plants have mitochondria if they can generate ATP in the chloroplast?
Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.
How is ATP produced in mitochondria and chloroplast?
ATP Synthase in Photosynthetic Organisms ATP synthases localized in the bioenergetic membranes of bacteria, mitochondria and chloroplasts produce the majority of ATP in aerobic cells at the expense of an electrochemical gradient generated by electron transfer reactions across the membrane.
How do mitochondria differ from chloroplasts in that mitochondria?
The main difference between chloroplast and mitochondria is their functions; chloroplasts are responsible for the production of sugars with the aid of sunlight in a process called photosynthesis whereas mitochondria are the powerhouses of the cell which break down sugar in order to capture energy in a process called
What is the function of mitochondria and chloroplast?
The function of chloroplasts and mitochondria is to generate energy for the cells in which they live. The structure of both organelle types includes an inner and an outer membrane. The differences in structure for these organelles are found in their machinery for energy conversion.
Where in the chloroplast does the cell concentrate hydrogen ions to power ATP synthase quizlet?
Hydrogen ions in the thylakoid space combine with electrons from the stroma at ATP synthase, releasing energy that can be used to produce ATP from ADP + Pi. A hydrogen ion from NADPH is used by ATP synthase to power the production of ATP from ADP + Pi, and an electron is released, splitting water.
