Q: Q: What is the name of a reactant in an enzymatic reaction? Read this paragraph and choose the correct option from the provided answers: Proteins Function as Enzymes If you were trying to type a paper, and every time you hit a key on your laptop there was a delay of six or seven minutes before you got a response, you would probably get a new laptop. In a similar way, without enzymes to catalyze chemical reactions, the human body would be nonfunctional. It functions only because enzymes function. Enzymatic reactionschemical reactions catalyzed by enzymesbegin when substrates bind to the enzyme. A substrate is a reactant in an enzymatic reaction. This occurs on regions of the enzyme known as active sites (Figure 2.27). Any given enzyme catalyzes just one type of chemical reaction. This characteristic, called specificity, is due to the fact that a substrate with a particular shape and electrical charge can bind only to an active site corresponding to that substrate. Choices: - membrane - Scar - tissues - substrate A:
A: substrate

Q: Q: Real gases deviate from ideal form at high pressure and what other thermodynamic condition? Read this paragraph and choose the correct option from the provided answers: Real gases deviate from ideal gases at high pressures and at low temperatures. Choices: - high winds - low pressure - high temperatures - low temperatures A:
A: low temperatures

Q: Q: Reef sponges typically have what type of beneficial relationships with other reef species? Read this paragraph and choose the correct option from the provided answers: Many sponges live on coral reefs, like the one in Figure below . Reef sponges typically have symbiotic relationships with other reef species. For example, the sponges provide shelter for algae, shrimp, and crabs. In return, they get nutrients from the metabolism of the organisms they shelter. Choices: - parasitic - microbes - mutual - symbiotic A:
A: symbiotic
