Three characteristics of enzymes​

Biology
1 answer:
levacccp [35]3 years ago
3 0

Enzymes are biological catalysts. They speed up reactions although they are not changed in the reaction. Enzymes are proteins, and therefore are folded chains of amino acids with a specific shape. This shape is determined by the sequence of amino acids held together by bonds, for example Hydrogen bonds. Enzymes speed up reactions by bringing reactants together and reducing the activation energy required to start the reaction (enzymatic reaction).

Enzymes are specific: they have a specific shape, therefore only a certain substrate will fit its active site. There are two theories of enzyme action: Lock and Key and Induced Fit.  The lock and key theory states that only a certain substrate will fit a certain active site, just like a key fits a lock. Induced Fit, likewise, states that enzymes wrap around substrates, attracted to each other by opposite charges, forming an enzyme substrate complex.

Gene testing is foolproof since it scans the building blocks of humans. Please select the best answer from the choices provided.
Harrizon [31]

False

reason -

Gene testing is not full proof as there are  possibilities of discrepancies in it based on the testing procedures used and the condition of sample. Since we human beings have the same genomic structure there are chances that our DNA may match with other people who do not share a heredity with our family. Basically statistical probability is used to determine probability of paternity, relationship of any kind etc. among two individuals . usually A 99% or higher percentage of probability is considered conclusive. and thus it gene testing can not be considered as full proof

Marina86 [1]

Answer:

How hard the blood pushes on the inside of the blood vessels is called Blood Pressure

The total amount of blood the heart pumps in one minute is called Cardiac Output

When blood vessels open wider during exercise, they are said to dilate

How many times your heart beats in one minute is called Heart Rate

The force that can put unhealthy tension on the heart as it is pumping is called Blood pressure

The amount of blood the heart pumps out in one beat is called Stroke volume.

Explanation:

All this concepts to the heart and cardiovascular system. It is important to know how heart is functioning to see how blood circulates.

lora16 [44]
They often respond to Quorum sensing which is determined by the cell density. Bacteria cells secrete molecules that can be detected by other bacteria, Quorum sensing allows bacteria to sense the concentration of these signalling molecules to monitor the local density of cells. It used by bacteria to coordinate certain behaviors , such as the production of biofilms.
