E)Krebs cycle/ cristae of mitochondria
Krebs cycle occurs inside the matrix of the mitochondria. Electron transport chain takes place in the cristae.
Soil composition would be best for availability of nutrients, water, and root development higher proportion of humus; lower amounts of clay and sand
Compared to the lower soil layers, the topsoil or surface soil often includes more organic matter and air but less clay. The topsoil typically has the highest concentration of plant roots and is more fertile than the other layers.
- Nutrient management includes managing the composition of the soil. Minerals, organic material, water, and air are the fundamental elements of soil. Typically, 45% of the soil is made up of minerals. 5% organic material 20–30% water and 20–30% air are used. At best, these percentages are merely generalizations.
- Numerous nutrients are found in soil, which are obtained from dead plants and animals. The plants eat these nutrients as nourishment. So soil contributes to the growth of plants by giving them sustenance in the form of nutrients.

Answer:
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
Explanation:
A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.
Answer:
Enzymes bind with chemical reactants called substrates there may be one or more substrates for each type of enzyme I beleivedepending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products the enzyme's active site binds to the substrate.
Explanation:

A typical restriction digestion reaction includes the DNA template, the desired restriction enzyme, a buffer, and occasionally BSA protein.
<h3>How come a restriction enzyme wouldn't function?</h3>
You should always check the expiration date, confirm that the enzyme has been stored at -20°C, and check the temperature of your freezer (do not allow temperatures to surpass -20°C, since many freeze-thaw cycles may cause an enzyme to lose action).
<h3>How does a restriction digest work?</h3>
With the aid of specialized enzymes known as restriction endonucleases (often referred to as restriction enzymes or REs), restriction digestion is the process of breaking down DNA molecules into smaller fragments.
