Main source of energy for reactions that occur in all living organisms is ATP.
The continental shelf is a gently sloping feature found at the edge of a continental landmass going seaward from the coast. Rivers that empty into the sea can produce currents that are strong enough to erode the material that builds the shelf. When this occurs channels or submarine canyons are formed. These canyons are deep and dark as no light can penetrate these regions. The canyons often lead out to sea towards the edge of the shelf.
Answer:
a) The response indicates that a pH below or above this range will most likely cause enolase to denature/change its shape and be less efficient or unable to catalyze the reaction.
b)The response indicates that the appropriate negative control is to measure the reaction rate (at the varying substrate concentrations) without any enzyme present.
c)The response indicated that the enolase has a more stable/functional/correct/normal protein structure at the higher temperature of 55°C than at 37°C because the enzyme is from an organism that is adapted to growth at 55°C.
Explanation:
Enolase catalyzes the conversion of 2-phosphoglycerate to phosphoenolpyruvate during both glycolysis and gluconeogenesis.In bacteria, enolases are highly conserved enzymes and commonly exist as homodimers.
The temperature optimum for enolase catalysis was 80°C, close to the measured thermal stability of the protein which was determined to be 75°C, while the pH optimum for enzyme activity was 6.5. The specific activities of purified enolase determined at 25 and 80°C were 147 and 300 U mg−1 of protein, respectively. Km values for the 2-phosphoglycerate/phosphoenolpyruvate reaction determined at 25 and 80°C were 0.16 and 0.03 mM, respectively. The Km values for Mg2+ binding at these temperatures were 2.5 and 1.9 mM, respectively.
Enolase-1 from Chloroflexus aurantiacus (EnoCa), a thermophilic green non-sulfur bacterium that grows photosynthetically under anaerobic conditions. The biochemical and structural properties of enolase from C. aurantiacus are consistent with this being thermally adapted.
Look at the clutch size. There seems to be no patterns between the amount of clutch size and the survival rate because if you have a low survival rate, you can have either a high or low clutch size based on the info that is given<span />
Answer:
<h2>approximately 4%</h2>
Explanation:
Given, frequency of recessive allele (p )= 0.02
so, the frequency of dominant allele is (q )= 1-p
so q = 1-p
p = 0.02
q = 1- 0.02
q = 0.98
Once we know p and q, which factor of the Hardy-Weinberg equation. we can calculate percentage of individuals who are carriers of lethal recessive allele.
so
Result : percentage of individuals who are carriers of the lethal recessive allele is 4%.
