When ATP synthase in activated it adds a phosphate group to what molecule?
ATP synthase catalyzes the addition of a phosphate group to an ADP molecule. ADP + ATP synthase + P --> ATP + ATP synthase (ATP synthase on both sides of the equation indicates that, as an enzyme, it is not used up in the reaction.)
Is it true that the region of atp synthase that catalyzes the production of atp from ADP and inorganic phosphate spans the chloroplast membrane?
False.
What is the difference between ATP synthesis and ATP synthase?
synthases do not use energy from NTP's, sythetases do! synthase can be used with any enzyme that catalyzes synthesis (whether or not it uses nucleoside triphosphates), whereas synthetase is to be used synonymously with 'ligase'.
Which of the following is false about the structure and function of ATP synthase?
At least 10 protons pass through ATP synthase in order to make a molecule of ATP.
What enzyme is responsible for synthesizing ATP?
The enzyme is ATP synthase (sometimes referred to as "ATP synthetase").It catalyzes the synthesis of ATP from ADP and free inorganic phosphate. It is a remarkable enzyme, part of which spins round. In fact, ATP synthase has been called a molecular machine.To see an image, use the link below.
What drives ATP synthase reactions the produced ATP?
Inside the intermembrane space, there is a buildup of hydrogen ions from the ETC. The hydrogen ions go down the concentration gradient through ATP synthase, producing ATP.
What powers the ATP synthase enzyme in the light-dependent reactions of photosynthesis?
Photosynthesis is the process that plants convert solar energy into the energy stored in chemical bonds. This consists of two reactions, light dependent and light independent.
What is used in the process of cellular respiration?
The two main enzymes that help catalyze Cellular Respiration are: Dehydrogenase - An enzyme that catalyzes a chemical reaction during which one or more hydrogens atoms are removed from a molecule NAD+ - Nicotinamide Adenie Dinucleotide - Coenzyme that can accept electrons during the redox reactions of cellular metabolism
Which of the following part(s) of ATP synthase is involved in catalysis?
Beta subunit
Describe the structure and function of the 4 subunits of ATP synthase?
ATP synthase is a multisubunit complex with four main parts, each made up of multiple polypeptides. Protons move one by one into binding sites on one of the parts, causing it to spin in a way that catalyzes ATP production from ADP and inorganic phosphate. The flow of protons behaves somewhat like a rushing stream that turns a waterwheel. ATP synthase is the smallest molecular rotary motor known in nature.
Where in the chloroplast are ATP and NADPH formed during the light reactions?
The light dependent reactions take place in the thylakoid of the chloroplast. ATP is formed in the ATP synthase protein by the assistance of the hydrogen gradient produced in the electron transport chain.
What spins to provide energy for adding a phosphate group to ADP?
The rotor part of the ATP synthase enzyme.
