Which term best describes a single female arctic fox?
Which term describes a single female arctic fox? biome.
Which term describes a single female arctic fox biome species ecosystem?
organism
What is a single population made of?
A single population is made of multiple organisms. In biology, population is a group of individuals which belongs to the same species that lives in the same area.
Which term is used to describe a group of Arctic foxes that live in a part of Alaskas Arctic National Wildlife Refuge?
Population
Which shows the levels of organizational hierarchy?
Answer Expert Verified. Community, population, ecosystem shows the levels of organizational hierarchy from least complex to most complex.
Which list of items would an ecological scientist most likely include when describing a forest community quizlet?
Answer Expert Verified The correct answer is deer, wolf, tree.
What is the largest organizational level found in one coral reef?
ecosystem
What would an ecological scientist include when describing a forest community?
When describing a forest community, an ecological scientist would most likely include deer, wolf, tree. These are the prerequisites for a forest community because in most forests there are deer and wolves, as well as trees.
What is a substrate quizlet?
Define substrate. A substance that interacts with an enzyme. Define product. Anything that is produced as a result of a reaction.
What is the definition of a substrate?
1 : substratum. 2 : the base on which an organism lives the soil is the substrate of most seed plants. 3 : a substance acted upon (as by an enzyme)
What is the name of the site where the substrate binds to the enzyme quizlet?
Active site
What does it mean that enzymes are substrate specific quizlet?
Enzymes are globular proteins which act as catalysts of chemical reactions. Molecules of substrate fit the active site and are chemically attached to it. Other molecules that do not fit therefore do not bind to the active site. This is how enzymes are substrate-specific.
What does it mean that enzymes are substrate specific?
Substrate specificity is also called as absolute specificity, since here the specificity is very high. Enzymes showing substrate specificity are specific only to one substrate and one reaction. Example: Enzyme lactase can only hydrolyze the β-1-4 glycosidic bond of lactose to yield galactose and glucose.
Can an enzyme only be used once?
An enzyme can only bind one reactant at a time. An enzyme speeds up a chemical reaction in the cell, but can only be used once.
What determines enzyme specificity?
The specificity of an enzyme denotes its ability to act selectively on one substance or a small number of chemically similar substances, the enzyme’s substrates. Like antibody specificity, enzyme specificity depends on a close fit between substrate molecules and their binding sites on an enzyme.
What are the 4 types of enzyme specificity?
Enzymes are specific to particular reactions. There are 4 types of specificity – absolute, group, linkage, and stereochemical.
Which of the following is a factor that contributes to the specificity of enzymes?
-An enzyme’s specificity is determined by the 3D shape of its active site. Regardless of which theory of enzyme specificity we are discussing (lock and key or induced fit), the active site determines which substrate the enzyme will react with.
Why do we need enzyme specificity?
Enzyme specificity is essential because it keeps separate the many pathways, involving hundreds of enzymes, that function during metabolism. Not all enzymes are highly specific. An enzyme therefore catalyzes a specific chemical reaction but may be able to do so on several similar compounds.
Why enzymes are highly efficient?
Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. Like all catalysts, enzymes take part in the reaction – that is how they provide an alternative reaction pathway.
Why can enzymes be used over and over again?
The substrate undergoes biochemical reaction. The structural configuration of the end products changes and does not match with the structural configuration of enzyme molecule. The enzyme is thus set free to combine with another substrate molecule and thus can be used over and over again.
