Epimysium- covers the entire muscle Perimysium- covers..? Endomysium- covers the individual muscle fibers Sarcomere- smallest contractile element of muscle fiber‚ extends from z-line to z-line Myofilament- responsible for contraction Striated- the color variations on the muscle fiber. Has to do with the amount of protein and the way it reflects light. Myosin- globular protein Bulb like heads come in contact with the active sites on actin Active sites are not exposed when in the resting position

which only select particles can enter the active site. For example‚ the enzyme amylase is only able to break down starch polymers. Changing the shape of an enzyme renders it useless. In this experiment‚ every group but the Popbeads group conducted a hydrolysis reaction. The Popbeads represented a condensation reaction. This is because every group but the Popbeads simulated a polymer (toothpick) being broken down. The Popbeads polymers were instead put together‚ creating a condensation reaction. An example

Nischal K. Karki William Carey University BIO 470 Cell Physiology Dr. Douglas Lipka Abstract Dynein is an ATPase from ATP associated with various cell activities family. Cytoplasmic dynein transports various materials from outside the cell to the center body. It is one of the few proteins that can convert the chemical energy of ATP into mechanical. It is a massive macro molecule that is involved with the movement of various organelles within the cell. It is also involved with the movement

Enzyme Assignment Research SBI4U Test A2 Table of Contents 1. What are the function roles and biological significance of the enzyme? Trypsin is part of the digestive system and degrades proteins‚ making it an enzyme known as protease. [1] It is one of the three principal digestive proteinases‚ the other two being pepsin and chymotrypsin. [9] Trypsin primarily hydrolyses peptides into smaller building-blocks‚ mainly amino acids (these peptides are the result of

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that
Premium Enzyme Catalysis Chemical reaction
Why does the subtle difference in how the simple sugar monomers are bonded in starch and cellulose affect how the two molecules are used? Cellulose is built from glucose molecules bonded covalently together through a process known as hydrolysis. Hydrolysis is a chemical process in which a molecule of water is added to a substance. Each alternating glucose ring of the cellulose molecule is flipped over and the water molecule (H2O) has been split out leaving an oxygen molecule between each ring

In Bio 202 one way we’ve learned to examine a cell is by taking advantage of the differences within the chemical reactivity of the molecules located within (Lab Manual‚ Chp. 5).

acidic medium and oxidative stress. An ideal stability indicating method is one that quantifies the standard drug alone and also resolves its degradation products. So described‚ different types of stress were used thermal‚ oxidation‚base hydrolysis and acid hydrolysis. Although unknown degradant peaks were observed in the acid‚ base‚ peroxide and thermal study‚ no degradant peaks were reported in the retention time(Rt) of lamivudine‚ zidovudine and nevirapine. Therefore‚ lamivudine‚ zidovudine and nevirapine
