PLEASE HELP ASAP Explain why a key that fits into a lock is a useful model for the function of enzymes.

Biology
1 answer:
kaheart [24]3 years ago
4 0

Answer:

<u>Keys(enzymes) are  specific to certain locks(substrate)</u>

Explanation:

<u>The key and lock model are used to illustrate the enzyme specificity to a substrate</u> function. Enzymes are specific in the reactions they catalyze. An enzyme will only catalyze one specific reaction or a group of closely related reactions.

For enzymes to catalyze a reaction, the substrate(s) must fit in the active site on the surface of the enzyme. This forms an enzyme-substrate complex. The enzymes speed up the formation of the products. The products formed separate from the enzymes so that other substrate molecules can fit into the active sites.

A) biome

Explanation - Biome is the ecological area where flora and fauna adapts themselves according to the environment or niche they are living in. An ecosystem is a group of living beings alongside the nonliving things of their condition, communicating as a framework.

Community is a group of organisms that interact with each other and carry out their work accordingly. Organism describes a particular being of a species. Therefore, Biome best suits the options given in the question.

How are proteins used in mating by Japanese beetles
cupoosta [38]

Japanese beetles store the lipids they need in proteins and during mating, to produce offspring they combine the male's proteins with the female's protein.

Is it possible to have a knockout mutant plant that shows no visible phenotype that is different from the wild-type plant?
joja [24]

Answer:

Molecular genetic approaches to the study of plant metabolism can be traced back to the isolation of the first cDNA encoding a plant enzyme (Bedbrook et al., 1980), the use of the Agrobacterium Ti plasmid to introduce foreign DNA into plant cells (Hernalsteens et al., 1980) and the establishment of routine plant transformation systems (Bevan, 1984; Horsch et al., 1985). It became possible to express foreign genes in plants and potentially to overexpress plant genes using cDNAs linked to strong promoters, with the aim of modifying metabolism. However, the discovery of the antisense phenomenon of plant gene silencing (van der Krol et al., 1988; Smith et al., 1988), and subsequently co‐suppression (Napoli et al., 1990; van der Krol et al., 1990), provided the most powerful and widely‐used methods for investigating the roles of specific enzymes in metabolism and plant growth. The antisense or co‐supression of gene expression, collectively known as post‐transcriptional gene silencing (PTGS), has been particularly versatile and powerful in studies of plant metabolism. With such molecular tools in place, plant metabolism became accessible to investigation and manipulation through genetic modification and dramatic progress was made in subsequent years (Stitt and Sonnewald, 1995; Herbers and Sonnewald, 1996), particularly in studies of solanaceous species (Frommer and Sonnewald, 1995).
