What else can I help you with?
What is a type of protein or RNA molecule that speeds up metabolic reactions in plants and animals without being permanently changed or destroyed?
Enzymes are biological catalysts that speed up metabolic reaction rates by lowering the reaction's activation energy. Proteins and RNA molecules can both function as enzymes.
Why do metabolic pathways require tens to hundreds of different enzymes?
Metabolic pathways require multiple enzymes to carry out specific chemical reactions at each step. Each enzyme catalyzes a specific reaction within the pathway, helping to regulate the overall flow of molecules and energy. This ensures that metabolic processes are efficient and tightly controlled.
What will happen to the enzyme active site after NADH binds there?
After NADH binds to the enzyme's active site, it will undergo a redox reaction where it donates electrons to the enzyme. This interaction may induce a conformational change in the enzyme, allowing it to carry out its catalytic function in the metabolic pathway.
What do you know about the consumption of an enzyme during a metabolic reaction in the body?
Enzymes are specialized proteins that facilitate chemical reactions in the body by lowering their activation energy, or the energy required to initiate a reaction. They are never consumed by the reaction themselves; therefore, enzymes can be re-used many times. Enzymes are specific to a particular substrate and usually facilitate the reaction by undergoing a conformational change when encountering the substrate, transforming it into a product or an intermediate.
What does the enzyme graph reveal about the reaction rate of the catalyzed reaction?
The enzyme graph shows that the reaction rate of the catalyzed reaction is faster compared to the uncatalyzed reaction. This indicates that the enzyme is effectively speeding up the reaction process.
How does enzyme accelerate metabolic reaction?
by lowering the activation energy needed
How enzyme accelerate metabolic reaction?
Enzymes lower the activation energy required to start the reaction.
What is an enzyme(what does it do for a chemical reaction)?
the purpose is to accelerate the process of the reaction...
How do enzymes accelerate a metabolic reaction?
Enzymes accelerate metabolic reactions by lowering the activation energy required for the reaction to occur. They do this by binding to substrate molecules and bringing them into the correct orientation for the reaction to take place. This increases the likelihood of the reaction occurring and speeds up the overall process.
What compounds catalyze metabolic reactions?
They are called enzymes; each one is specific for one metabolic reaction.
What protein in cytosol accelerate metabolic reaction?
Enzymes are proteins in the cytosol that accelerate metabolic reactions by decreasing the activation energy required for the reaction to occur. Enzymes function as biological catalysts, allowing the cell to carry out complex biochemical processes at a faster rate.
Which part of a chemical reaction is most changed by enzyme activity?
The speed of the reaction is most changed by enzyme activity, as enzymes can greatly accelerate the rate at which chemical reactions occur by lowering the activation energy required for the reaction to proceed.
An enzyme is a biomolecule that increases the rate of a chemical reaction. An enzyme is a kind of?
An enzyme is a kind of protein that acts as a catalyst in biochemical reactions, facilitating the conversion of substrates into products. By lowering the activation energy required for reactions, enzymes accelerate metabolic processes essential for life. Some enzymes are also made of RNA, known as ribozymes, which can catalyze specific reactions as well.
What end product from a metabolic pathway binds to an enzyme involved in a reaction at the beginning of the pathway. changing the shape of the active site and preventing the enzyme from?
The end product of a metabolic pathway can bind to the enzyme involved in the beginning of the pathway, acting as an inhibitor. This typically changes the shape of the enzyme's active site, preventing the enzyme from binding to its substrate and carrying out the reaction. This regulatory mechanism is known as feedback inhibition.
Which of the following is not used to determine metabolic activity?
Temperature is not typically used to determine metabolic activity, as metabolism is more directly influenced by factors such as enzyme activity, substrate availability, and hormonal regulation. Temperature can indirectly affect metabolic rate by influencing enzyme function and reaction rates.
Which method of enzyme control is when the products of a reaction inhibit the working of an enzyme by binding to the enzyme?
The method of enzyme control where the products of a reaction inhibit the enzyme by binding to it is known as feedback inhibition. In this process, the end product of a metabolic pathway binds to an enzyme involved in the pathway, reducing its activity and preventing the overproduction of the product. This regulatory mechanism helps maintain homeostasis and balance within the cell.
What is a enzyme controlled reaction?
An enzyme-controlled reaction is a biochemical process in which an enzyme acts as a catalyst to accelerate the rate of a chemical reaction without being consumed in the process. Enzymes lower the activation energy required for the reaction to occur, allowing substrates to convert into products more efficiently. These reactions are highly specific, meaning that each enzyme typically catalyzes only one type of reaction or acts on a specific substrate. Enzyme activity can be influenced by factors such as temperature, pH, and the concentration of substrates or inhibitors.
