In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.

Q: The Milky Way is a barred spiral galaxy with a diameter between 150,000 and 200,000 light-years (ly). It is estimated to contain 100 -- 400 billion stars. There are probably at least 100 billion planets in the Milky Way. The Solar System is located within the disk, 26,490 (± 100) light-years from the Galactic Center, on the inner edge of the Orion Arm, one of the spiral-shaped concentrations of gas and dust. The stars in the innermost 10,000 light-years form a bulge and one or more bars that radiate from the bulge. The galactic center is an intense radio source known as Sagittarius A *, likely a supermassive black hole of 4.100 (± 0.034) million solar masses.

A: how many planets in our milky way galaxy

Q: The Canada Act 1982 (1982 c. 11) is an Act of the Parliament of the United Kingdom that was passed (as stated in the preamble) at the request of the Parliament of Canada, to 'patriate' Canada's constitution, ending the necessity for the British parliament to be involved in making changes to the Constitution of Canada. The Act also formally ended the 'request and consent' provisions of the Statute of Westminster 1931 in relation to Canada, whereby the British parliament had a general power to pass laws extending to Canada at its own request.

A: when did canada gain its independence from britain

Q: The mechanism of enzyme catalysis is similar in principle to other types of chemical catalysis. By providing an alternative reaction route the enzyme reduces the energy required to reach the highest energy transition state of the reaction. The reduction of activation energy (Ea) increases the amount of reactant molecules that achieve a sufficient level of energy, such that they reach the activation energy and form the product. As with other catalysts, the enzyme is not consumed during the reaction (as a substrate is) but is recycled such that a single enzyme performs many rounds of catalysis.

A:
how does an enzyme cause a reaction to increase in rate
