of juices is 2 to 3 L per day. Hydrochloric acid and enzymes are also produced by cells of the stomach. All these substances are mixed with the food and break it down. Crushed‚ it is transformed into liquid‚ the chyme. At this stage‚ the chyme is at the level of the pylorus. It is then propelled little by little into the small intestine by contraction of the stomach. Generally‚ the stomach will empty in about 4 hours after a

HYDROGEN PEROXIDE INTRODUCTION Enzymes function similarly to a lock a key mechanism where only one specific key will work (U and Fischer‚ 1994). An enzyme is a macromolecule that acts to increase the rate of either a substrate breaking down into two or more products‚ or where two substrates join up to form one product (Dundon‚ 2018). These enzymes perform this by lowering the activation energy required for the reaction to occur under normal conditions. For the enzymes to lower the activation energy

A company has specified that the acceptable size of a knob that is to be produced is (0.140 ± 0.003) inches. In this lab‚ the dimensions of the knobs produced in one day are tested for discrepancy in order to pass control testing. This lab also reports the probability that knobs with the acceptable dimension will be produced. MATERIALS AND METHODS Using Microsoft Excel‚ a histogram was created displaying the three documented dimensions of 15 batches of knobs. This histogram was obtained in order

Transpiration Formal Lab Report By Jessica Tran Introduction When water is transported from the roots to the mesophyll cells in the leaves‚ it is evaporates out the stomates‚ called transpiration‚ to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomates open to release water‚ it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis

For information on how this assignment will be graded‚ please visit the Course Information sectionChlorophyll and Accessory Pigments A pigment is any substance that absorbs light. The color we see comes from the wavelengths of light that reflect. Chlorophyll‚ the green pigment common to all photosynthetic cells‚ absorbs all wavelengths of visible light except green. The green reflects back to our eyes

pH higher than 5. The stomach average pH level‚ being between 1.5-3.5‚ directly correlates to the most efficient pH levels for invertase activity‚ perhaps supporting the theories that either enzymes adapted to our stomach acid’s pH or the human body’s anatomy adapted to the sustainable pH range of the enzyme (Lehrer). However‚ it is likely that there is not enough structural

good model. The model superimposed very well to evolutionary related protein AXE2 with an RMSD (Root Mean Square Deviation) of 0.217 Å. In Fig. 5a‚ the predicted model‚ has been shown with overlaid catalytic triad residues and the loop involved in catalysis. The position of Ser- His- Asp (catalytic triad) was quite similar to the predicted residue position of 15‚ 192 and195 respectively‚ as described earlier in Fig 1b. Notably‚ In the Fig 5a‚ the orientation of the active side loop was significantly

of synthesis: 1- In pancreas: Synthesis of taurine in the mammalian pancreas occurs through the cysteine sulfinic acid pathway. First‚ in this pathway is oxidation of cysteine sulfahydryl group to sulfonic acid‚ this oxidation is catalyzed by the enzyme cysteine dioxygenase. In turn‚ cysteine sulfonic acid is decarboxylated to hypotaurine by sulfonoalanine decarboxylase. It is not well known whether hypotaurine is then enzymatically or spontaneously oxidized to taurine. 2- in CNS: Biosynthesis of
