Ответ:

АНТАГОНІСТИ - це ліганди, які перешкоджають зв’язуванню агоністів з рецепторами і таким чином блокують їхню дію. А. не чинять фармакологічної дії, пов’язаної з рецепторами. Напр. пропранолол є а. β-адренорецепторів. Зв’язуючись з ними в серці, він запобігає викликаній катехоламінами тахікардії у відповідь на фізичне навантаження.

Текст:
Understanding British meals is one of the great mysteries to the foreign visitor. Over the centuries, the British have shown a tendency to name and rename their meals, and to move them about the day in an apparently random fashion. Further to confuse outsiders, we give different names to each meal depending on our social class and part of the country we live in.

Breakfast, which was once taken at 5 o’clock in the morning, can now be at any time before 11.30. It has thus overtaken dinner. In Norman times – the 12th century – dinner was at 9 am; by the 15th century it had moved to time between noon and 2.30 in the afternoon and is called lunch by a large proportion of the population, especially the middle and upper classes and people form southern Britain. Many farm labourers, however, who start work at sun-rise and have their breakfast before they go to work, still stop for a lunch break at about 9 o’clock.

In the 14th century, supper was at 4 o’clock – which is now called teatime. But outside the south-east of England, working families have tea or high tea at about 6 in the evening while the rest of their fellow-countrymen have dinner, which is often also called supper, at about 7.30 pm.
