Answer:
Aerophobia
Explanation:
A phobia is an irrational fear of something. It can persist even when we know that we will not be harmed.
Aerophobia is the fear of flying or being on a flight (aeroplanes, helicopters, etc.). Experiencing this fear will often result in extreme anxiety and discomfort. Some doctors prescribe anti-anxiety medication for people who have aerophobia and need to take a flight.
It gives the cell a net gain of 2 ATP molecules for each molecule of glucose that enters glycolysis
A) Crest
B) Amplitude
C) Trough
D) Wavelength
A) Between pH 1 and 6. This is because within this range, the enzyme activity is nonzero, whereas outside the range it is zero
b) Optimum pH. This is simply because it is the pH for which an optimum enzyme activity is achieved, maximising the rate of reaction
The final question requires a little more explanation. At this level we work with the lock and key hypothesis, that is to say the enzyme only catalyses the reaction when the substrate(s) collide with the active site with the correct orientation and minimum activation energy is exceeded. The enzyme is specialised to the substrate, so the active site (where catalysis by adsorption/desorption occurs) is a very specific shape to fit it. In denaturing, the active site changes shape such that it is no longer specialised to the substrate. The lock is no longer the right shape for the key, so the enzyme no longer works.
This denaturing can be caused by extremes in pH, where ionic interactions with H+ or OH- break bonds in the protein, or by high temperature breaking these bonds.
I hope this helps you :)
Answer:
Explained below:
Explanation:
When a proto-oncogene changes then it becomes a "bad" gene called an oncogene that can enhance activated forever when it is not presumed to be. When this occurs, this will grow the cell out of control, yet if the initial trigger is removed his unnatural growth normally produces a mass, thus the tumor is formed. Benign tumors comprise osteophytes, uterine fibroids, and melanocytic nevi which are restricted and limited and do not convert into cancer but Potentially malignant neoplasms constitute carcinoma in situ. which are limited, do not invade and finish but in the future, they may convert into cancer.
