Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.
Based on the data, which trait do you think is dominant versus recessive? Explain the information you used to help you determine this. Based on your answer, how would you write the genotypes of the original parental generation for this cross?
- Dihybrid cross is the mating of two parents of the same species having two different traits or two different genes responsible for different phenotypes.
- The traits can be of two types: Dominant (indicated by captial letter code) and recessive (indicated by small letter code).
- In dihybrid cross, the parents will be heterozygous.
- The F1 generation has phenotypic ratio of 9:3:3:1.
