B) All enzymes are proteins: Enzymes are biological catalysts that speed up reactions by creating a second pathway for the reaction to take place. They are protein molecules that come in a variety of shapes and sizes, each serving as a catalyst for various reactions....
a酶是一种生物催化剂,它具有作用专一性强、催化效率高等特点,能在常温常和低浓度条件下进行复杂的生化反应。没有酶,就没有了生物体的一切生命活动。酶工程师研究酶的生产和应用的一门技术性科学。 The enzyme is one biocatalyst, it has the function specificity strongly, the catalyzed efficiency higher charact...

Most enzymes are made from amino acids. Enzymes are catalysts in the body, which means that they make chemical reactions go faster, but are not changed by the reaction. Hormones are also made up largely of amino acids. Hormones are used to pass messages around the body instructing our organs...
a我们如此的听话以至于老师很开心 We like this are obedient teacher to be very happy[translate] a我们该去上学了吗? We should go to go to school?[translate] aEnzymes display enormous catalytic power,accelerating reaction rates as much as 106～1013 over chemical catalysts levels 酵素显示极大的催化...
Enzymes Enzymes work to speed up the process of a chemical reaction, but in doing so, are not permanently changed or used up as a result of the reaction. Enzymes help convert molecules of substrate into product. There are many different classes of enzymes in ...
Enzymes are essential biological catalysts that speed up chemical reactions in living organisms without being altered themselves. This article provides a thorough overview of enzyme activity, including the critical roles of enzymes, enzyme classification systems, kinetics, common assays, and the … Read ...
Bacterial group I introns: mobile RNA catalysts Group I introns are intervening sequences that have invaded tRNA, rRNA and protein coding genes in bacteria and their phages. The ability of group I introns to self-splice from their host transcripts, by actin... Authors: Georg Hausner, Mohame...

and the bacteria have enzymes that act as catalysts that eventually add nitrogen to the soil, enriching it.In the second case, pollinators (insects, birds) obtain food from the flowering plant, and the plant has its pollen distributed and seeds dispersed much more efficiently than they would ...
