A major theme of science fiction and of speculative biology is to convey a message of optimism or pessimism according to the author's worldview. [5] [6] Whereas optimistic visions of technological progress are common enough in hard science fiction, pessimistic views of the future of humanity are far more usual in fiction based on biology. [4]
The substrate is activated in a small part of the enzyme's macromolecule called the active site. There, the binding of a substrate close to functional groups in the enzyme causes catalysis by so-called proximity effects. It is possible to create similar catalysts from small molecules by combining substrate-binding
In the popular science fiction franchise Star Trek several bioships appear. The Star Trek: The Next Generation episode "Tin Man" features a bioship as the main part of the plot. Species 8472 also has an enormous fleet of bioships which are able to go toe to toe with arguably the Federation's most malignant enemy, The Borg.
Science in science fiction is the study or of how science is portrayed in works of science fiction, including novels, stories, and films. It covers a large range of topics. Hard science fiction is based on engineering or the "hard" sciences (for example, physics, astronomy, or chemistry).

Katakana: ヒヒイロカネ or kanji: 緋々色金 It is a red-orange fantasy metal that is common in Japanese fiction. Hyperium: Giants series One of three stable transuranic elements predicted by the new science of nucleonics in James P. Hogan's Giants series. Not naturally occurring outside of neutron stars, but trace amounts are created in ...
A bioactive compound is a compound that has an effect on a living organism, tissue or cell, usually demonstrated by basic research in vitro or in vivo in the laboratory. While dietary nutrients are essential to life, bioactive compounds have not been proved to be essential – as the body can function without them – or because their actions are obscured by nutrients fulfilling the function.
In molecular biology, substrate presentation is a biological process that activates a protein. The protein is sequestered away from its substrate and then activated by release and exposure to its substrate. [1] [2] A substrate is typically the substance on which an enzyme acts but can also be a protein surface to which a ligand binds. In the ...
