the flow of what particle across the thylakoid membrane powers the production of atp course hero

Is oxygen a product or byproduct of thylakoid?

Only ATP is formed and oxygen is a byproduct. e. ATP and NADPH are formed, and oxygen is a byproduct. 21. Hydrogen ion flow in the thylakoid

How are PGAL molecules formed from PGA and NADPH?

46. PGAL molecules are formed from the reaction of PGA molecules with ATP and NADPH. d. Calvin-Benson cycle e. C4 pathway 47. Carbon dioxide combines with RuBP d. Calvin-Benson cycle e. C4 pathway 48. This process yields NADPH as well as ATP. d. Calvin-Benson cycle e. C4 pathway 49. This is a carbon-fixing system that precedes the d.

What combines with RuBP to produce NADPH and ATP?

Carbon dioxide combines with RuBP d. Calvin-Benson cycle e. C4 pathway 48. This process yields NADPH as well as ATP. d. Calvin-Benson cycle

Which ion is pumped across the thylakoid membrane to make ATP?

H+During the electron-transport process, H+ is pumped across the thylakoid membrane, and the resulting electrochemical proton gradient drives the synthesis of ATP in the stroma.

What moves across the thylakoid membrane?

The electron transport chain moves protons across the thylakoid membrane into the lumen (the space inside the thylakoid disk).

How is ATP formed in the thylakoid lumen?

Protons diffuse out of the thylakoid lumen through the enzyme, ATP synthase, producing ATP in the process. Once the electron reaches PSI, it joins its chlorophyll a special pair and re-excited by the absorption of light.

Where does energy come from to operate ATP synthase in the thylakoid membrane?

Thylakoid membrane-localized chloroplast ATP synthases use the proton motive force generated by photosynthetic electron transport to produce ATP from ADP.

Is ATP synthase found in the thylakoid membrane?

Respiratory Chain and ATP Synthase The ATP synthases comprise a very large group of highly conserved enzymes that are found in the bacterial cytoplasmic membranes, the thylakoid membranes of chloroplasts, and the inner membranes of mitochondria.

Why do hydrogen ions flow from the thylakoid space to the stroma through ATP synthase?

Why do hydrogen ions flow from the thylakoid space to the stroma through ATP synthase? A. They are pumped actively through ATP synthase. This uses up ATP energy and causes the production of ADP and phosphate.

How is ATP produced?

ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen.

What is produced in thylakoid membrane?

The thylakoid membranes of plant chloroplasts contain assemblies which utilize light energy to generate ATP and NADPH.

How ATP is formed in photosynthesis?

The ATP is produced during the light reaction of photosynthesis by photophosphorylation. ATPs are produced towards the stromal side of the thylakoid membrane. The light energy is absorbed and stored in the high energy compounds, namely, ATP and NADPH.

How does ATP synthase obtain the energy to produce ATP quizlet?

How does ATP synthase obtain the energy to produce ATP? Hydrogen ions flow down a concentration gradient from the thylakoid space to the stroma through ATP synthase, releasing energy that can be used to produce ATP from ADP + Pi.

Which of the following is the location for the ATP synthase in photosynthesis?

ATP plays a central role in cellular metabolism. [1] It is the most important donor of free energy in any biological system. In eukaryotes, its synthesis takes place in the mitochondria – during respiration – and in the chloroplasts – during photosynthesis.

What protein allows protons to flow from the lumen to the stroma of the thylakoid resulting in the phosphorylation of ADP to generate ATP?

The ATP synthaseThe ATP synthase is a large protein complex consisting of about 24 protein subunits. It acts as a channel through which protons that are in the thylakoid lumen can escape back into the chloroplast stroma, driven by the electrochemical gradient.
