Water is the compound. Iodine and calcium are elements, and air is a mixture
The correct option is 3.
Enzymes are biological catalysts which speed up the rate of biochemical reactions inside the cells. Enzymes are very specific in action and they require specific conditions called optimum conditions for them to function optimally.
When the optimum conditions are not met, an enzyme's activity will be lowered or totally stopped.
Conditions that affect the optimum activity of an enzyme include: temperature, pH level and regulatory activity of regulatory enzymes and hormones.
B positive patients can receive blood from B positive, B negative, O positive and O negative donors.
Answer:NADH donates it electron to complex I a higher energy level than other complexes while FADH donates it electron to complex II a lower energy complex.
Explanation:
Both NADH and FADH are shuttle of high energy electrons originally extracted from food into the inner mitochondrial membrane.
NADH donate it electron to a flavoprotein consisting of FMN prosthetic group and an iron-sulphur protein in ETC complex-I. Two electrons and one hydrogen ion are are transferred from NADH to the flavin prosthetic group of the enzyme.
While the electrons from FADH2 enters the ETC (electron transport chain) at the level of co-enzyme Q (complex II). This step does not librate enough energy to act as a proton pump.
So NADH produces 2.5 ATP during the ETC and oxidative phosphorylation because it donates its electron to Complex I, which pump more electrons across the membrane than other complexes.
Answer:
Urologist
Explanation:
The person who is involved in the study of the genitourinary system of both males and female is known as the urologist.
The genitourinary system is the system of the organs which are involved in both the sexual and urinary function in the body. The word is formed by the uro from urine and logist- for the person who studies forms the word urologist.
Thus, the urologist is the correct answer.
