No coloque ningún plástico en el horno, incluidas las cestas o bandejas de plástico para sostener la cristalería. Las esporas de las bacterias son muy resistentes al calor y no se eliminan por ebullición a presión atmosférica. En el aula, se puede usar una enlatadora a presión para esterilizar líquidos.

What makes up the "tail" of an ATP molecule? 3 phosphate groups ribose adenine 2 phosphate groups
ZanzabumX [31]

Answer:

The tail of an ATP molecule is made up by 3 phosphate groups link together by the help of 2 high energy phospho anhydride bonds.

Explanation:

ATP or adenosine tri phosphate is an energy rich compound that contain adenine base, ribose sugar and 3 phosphate groups.

                  These 3 phosphate groups makes up the tail of ATP molecule.The 3 phosphate groups are designated as alpha phosphate,beta phosphate and gamma phosphate starting from the C5 atom of ribose sugar.

          When ATP undergo hydrolysis the terminal phosphate group or the gamma phosphate group is cleaved from the ATP molecule resulting in the formation of ADP and inorganic phosphate along with the generation of high amount of free energy that is utilized by the cell to perform various cellular and physiological activities.

A scientist observes that, when the pH of the environment surrounding an enzyme is changed, the rate the enzyme catalyzes a reac
vredina [299]

Answer:

A- A pH change can cause the enzyme to change its shape

Explanation:

A rise or fall in the pH of the medium from the optimum of pH 7 usually affect  the  enzymes' active sites  of  and therefore the  shape and  the  rate of enzyme activity.

Assuming  the pH is too low, the enzyme medium becomes acidic;Acidosis. The high Hydrogen ions concentration  interacts with the R-groups of the amino acids moiety of the enzymes, this interaction affects the ionization of the  R-groups, disrupting the ionic bonding holding these R-groups in shape.

This results in loss of the 3-Dimensional shape arrangements of the protein molecule  and therefore of the active sites. Since active sites of  enzymes  determines the specificity of the <u>enzymes substrate- complex </u> to give <u>enzyme-product complex,</u> the catalytic activity of the enzymes decreases, <u>the rate of  reaction decreases,and products formation stops, and the reaction also stops.</u>

The same is applicable to extremely high pH=Alkalosis.

However, the effective buffer system of the body prevents this scenarios from happening in real sense in the body. Through mopping by the  haemoglobin, excretion by the kidney, etc

The structure of a human skin cell differs from that of a human muscle cell. The two cells most likely have different __________
AnnyKZ [126]

Answer:

The correct answer would be - functions.

Explanation:

The structure of the skin cells and muscle cells are different and have a different number of cell organelles on their role in the body. Skin cells are a special type of cells that keep on shedding and replaced by new ones therefore they need less energy and have many mitochondria.

In contrast, muscle cells have different structures as they need a high amount of energy to make movements and therefore have lots of mitochondria in the cell.
