Within cells, the cytoplasm is made up of a jelly-like fluid, called the cytosol, and other structures that surround the nucleus. Cytoskeleton. The cytoskeleton is a network of long fibers that make up the cell's structural framework
Answer:
-Due to acidic pH of stomach.
Explanation:
Enzymes are generally made up of protein molecules and work at an optimum pH and temperature. This is because at change in pH and temperature leads to denaturation of proteins that cause change in active site of enzyme.
For trypsin, optimum pH is slightly basic as pH (7.5). So, trypsin would become non-functional at acidic pH due to denaturation and loss of active site.
Trypsin is a pancreatic enzyme that works at small intestine as pH of small intestine is slightly basic.Thus, if the trypsin was secreted in stomach instead of pancreas, it would be non-functional as stomach has acidic pH due to stomach acid.
<em>paper is better</em> because its made of natural materials and the earth can absorb and decompose it.<em><u> Plastic is worse</u></em> because can get caught around animals necks and can be eaten which will cause stomach issues and later death.
"These" should be referring to Alkali Metals.
They include metals such as Lithium, Sodium, Potassium etc.
They're classified as Group I elements because they all have one outmost shell electrons. This is why these metals are so reactive because they only need to lose one electron in order to achieve the octet of electrons (or duplet for Lithium), which means complete outmost shell electrons (2 or the 1st shell, others are 8).
The reason why they're especially reactive to Halogens (Group VII) elements are that Halogens have 7 outmost shell electrons, which only needs one more electron in order to get to the octet of electrons. So, if an Alkali metal reacts with a Halogen, the metal would give one of their electrons to the Halogen, that way, both of the elements can have an octet of electrons (or duplet).
Hey there!
Enzymes can be reused over and over again
