What is the effect of excess heat or temperature on an enzyme-?
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.
A different enzyme controls each step of what?
A different enzyme controls each step of a metabolic pathway. This ensures that each chemical reaction in the pathway is tightly regulated and allows for efficient energy usage and production.
A given enzyme works on?
specific substrates to catalyze a biochemical reaction. Each enzyme has a specific substrate or group of substrates that it acts on, and the enzyme's active site is designed to bind to these substrates. This specificity ensures that the enzyme functions effectively in the body.
Is a new enzyme molecule needed each time a reaction occurs?
yep
What is enzyme affinity?
Enzyme affinity refers to the strength of binding between an enzyme and its substrate. It determines how readily an enzyme can bind to its substrate and catalyze a reaction. Enzymes with high affinity have a strong binding interaction with their substrates, leading to efficient catalysis.
Beadle and Tatum showed that a gene codes for an enzyme using bread what?
Beadle and Tatum used bread mold (Neurospora crassa) to demonstrate that each gene is responsible for encoding a specific enzyme in a biochemical pathway. By creating mutants that were unable to produce certain enzymes, they showed how mutations in specific genes can disrupt metabolic pathways. This work laid the foundation for the "one gene, one enzyme" hypothesis.
What enzyme speeds up a chemical reaction is known as?
All enzyme's are catalysts for certain chemical reactions. Each enzyme will only work with a certain substrate one analogy being that the enzyme is a key and the substrate is a keyhole, and each enzyme has a unique enzyme.
How do a person get PKU?
Phenylketonuria (PKU) is an inherited metabolic disorder caused by a mutation in the gene responsible for producing the enzyme phenylalanine hydroxylase. This enzyme is necessary for breaking down the amino acid phenylalanine, which is found in many protein-containing foods. PKU is inherited in an autosomal recessive pattern, meaning that a person must receive two copies of the mutated gene, one from each parent, to develop the condition. If both parents are carriers of the PKU gene mutation, there is a 25% chance with each pregnancy that their child will have PKU.
What is the type of mutation that causes Leukemia disorder?
It's a gene mutation. And it is different for each organ.
What is the effect of excess heat or temperature on enzyme?
Each enzyme has its ideal temperature
Beadle and tatum's hypothesis?
beadles and tatums hypothesis was that mutations occured when one gene made two poteins it was evidential that beadles and tatums hypothesis had altered in 1941 when tatum found a mutation in one of there experiments.
Do the amino acids that are in the active site of an enzyme have to be near each other in the enzyme's primary structure?
no
What is the definition of enzyme specificity?
each enzyme has a specific substrate to which it binds through a definite active site and any other enzyme can not bind to it
What is the effect of excess heat or temperature on an enzyme-?
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.
How many loaves of bread to Americans eat each year?
On average, Americans consume around 53 pounds of bread per year, which equates to about 150 loaves of bread.
A different enzyme controls each step of what?
A different enzyme controls each step of a metabolic pathway. This ensures that each chemical reaction in the pathway is tightly regulated and allows for efficient energy usage and production.
What are the sources of genetic variation in plants and each of the major pathogen groups?
mutation
