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.
Answer:
They are all carbohydrates.
Explanation:
Homo polysaccharides include starch, glycogen, and cellulose (same type of sugar-all made of glucose).
1- Amylose and Amyloprotein are the components of starch. Amylose is a branched chain with alpha 1–4 and alpha 1–6 at the branch point, whereas Amylopectin is a linear chain with alpha 1–4 and alpha 1–6 at the branch point.
2- Glycogen is created by forming a branched chain from glucose at alpha 1–6. It has a lot of branches.
3- Cellulose is a linear chain of glucose molecules with beta bonds.
Starch and glycogen serve as short-term energy stores in plants and animals, cellulose found in plant cell wall only.
Answer:
Geographical Isolation
Explanation:
Lava serves as geographical barrier to separate the two populations of monkey. These two isolated populations accumulate variations and gradually become reproductively isolated. Reproductive isolation brought about by geographical isolation leads to formation allopatric species which are now present in different geographical regions.
The third one is the product of cellular respiration
Answer:
just trying to get more points because I need them also this old so yeah
Explanation:
yeah yeah yeah yeah
