The film "Dekada 70" is a powerful and emotional depiction of the tumultuous events that occurred in the Philippines during the 1970s. The movie follows the story of a middle-class family as they navigate the challenges and dangers of living under the authoritarian regime of Ferdinand Marcos.
The film does an excellent job of capturing the political and social climate of the time period. The government's heavy-handed tactics and corruption are clearly portrayed, and the fear and uncertainty felt by the characters are palpable. The movie also touches on important themes such as resistance, repression, and the power of individual action.
One of the most striking aspects of "Dekada 70" is the way it portrays the impact of political upheaval on ordinary people. The main character, Amanda, is a housewife who becomes increasingly involved in the resistance movement as she witnesses the suffering of her husband and children at the hands of the government. Amanda's transformation from a passive observer to an active participant in the struggle for change is a poignant reminder of the power of ordinary people to effect change.
The acting in the film is superb, with Vilma Santos giving a particularly powerful performance as Amanda. The supporting cast is also strong, with excellent performances from the rest of the family members. The film's cinematography and production design are also top-notch, with the movie's period setting being convincingly brought to life.
Overall, "Dekada 70" is a moving and powerful film that offers a poignant portrayal of a difficult and tumultuous time in Philippine history. It is a must-see for anyone interested in the political and social history of the Philippines, or for anyone looking for a thought-provoking and emotionally satisfying movie experience.
Effect Of Temperature On Enzyme Catalase Activity In A Potato Report Example
I showed that temperatures affect the reaction rate between hydrogen peroxide and catalase enzymes. How many iron chains are in a catalase? Independent: Temperature 10c, 37c, 60c using three different water baths each adjusted to a specific temp. My results clearly show that catalase activity increases with increases in temperature until the enzyme becomes denatured destroyed and it no longer functions as a catalyst. With extremely high temperatures, an enzyme will change shape because the intermolecular forces within the enzyme weaken and it cannot perform the function it usually does. Insert test tube A, leave for a 3 minutes before using the 10mL pipette to add 8mL H2O2 to the test tube. What is the effect of excess heat or temperature on an enzyme? Which is the best pH for catalase to work? This means that temperature has hardly any effect on the rate of reaction with catalase.
What temperature does catalase best function in?
At what temperature is catalase and peroxidase inactivated? Select all that apply. This was an inaccurate method. Stevens, "Vitamins C and E: Beneficial effects from a mechanistic perspective. Extremes of high temperatures denature enzymes, which stops their action Sells, 1999. Kaplan, "Purification and properties of the catalase of bakers' yeast," Journal of Biological Chemistry, vol.
How Does Temperature Affect Catalase Enzyme Activity?
What is the optimal condition for catalase? Vale, "Hydrogen peroxide poisoning," Toxicological reviews, vol. The preferred temperature for catalase falls between the ranges of thirty five to fifty degrees Celsius 4. Tell us clearly what the results were for catalase from the two sources. A peroxidase is an enzyme that acts as catalysts, which occurs in biological systems. Catalase activity decreases after optimal temperature. How does temperature affect Catecholase? Laboratornoe Delo 1 : 16—19. Journal of Molecular Biology.
How does temperature affect catalase enzymes?
The liver sustains a neutral pH of about 7, which creates the best environment for catalase and other enzymes. What is the Optimal Temperature for Enzymes? How does temperature affect catalase activity? What was the optimum temperature of catalase? Most other enzymes function within a working pH range of about pH 5-9 with neutral pH 7 being the optimum. Effect of Freezing on Enzyme Activity At the point of freezing, molecular motion decreases drastically as solid formation occurs and molecules are locked into rigid crystalline formations. As hydrogen peroxide enters the active site of the catalase enzyme, it interacts with two amino acids, causing a proton to transfer between the oxygen atoms. Why is 40 degrees the optimum temperature for enzymes? As the temperature increases so does the rate of enzyme activity. Basak, "Human catalase: looking for complete identity," Protein and cell, vol. Because the molecules are spread apart, they take up more space.
Optimum Temperature Of Catalase
Studying the effect of temperature and substrate concentration on enzyme concentration allows better understanding of optimum conditions which enzymes can function. In contrast, enzymes from thermal vent bacteria have been forced to evolve so that they can remain stable at far higher temperatures. Provide details and share your research! These reagents were placed in large bottles and were labeled with a sharpie. It was expected that an extreme temperature would decrease the rate of reaction and results observed support that idea. Oxygen is a gas and therefore wants to escape the liquid. If not, and you accidentally use too high a temperature, you risk denaturing the enzymes and losing their desired activity.
The Biological Temperature Of Catalase
Once the temperature goes beyond optimum, the rate of reaction… Catalase Lab In this laboratory exercise we studied enzyme catalase, which accelerates the breakdown of hydrogen peroxide into water and oxygen. The assay system, in which a filter paper disc was dipped into the enzyme and submerged using a stirring rod in a test tube filled with 20mL of hydrogen peroxide, was used to test several enzyme factors. Enzymes work best when there is a high enough substrate concentration for the reaction they catalyse. Increasing temperature increases the kinetic energy of the particles which means that an increase in temperature will increase the speed of the hydrogen peroxide and the catalase molecules which Effect Of Temperature On Amylase 1167 Words 5 Pages Research question What is the effect of temperature Amylase activity? Why does freezing increase catalase? Proceedings of the National Academy of Sciences of the United States of America. Catalase is an enzyme found in most cells and helps decompose hydrogen peroxide into oxygen and water.
What was the optimum temperature of catalase?
Role in Living Organisms Although its ability to break down a toxic molecule such as hydrogen peroxide might make catalase seem to be an indispensable commodity, mice engineered to develop without catalase have a normal physical appearance. How does freezing affect enzymes? RCSB Protein Data Bank. Effect of pH on peroxidase activity. If this results in altering the "fit" of the enzyme to its substrate, the speed at which the reaction occurs may be slowed or the reaction may not occur at all. At a pH level lower or higher than this range, the catalase stops working.
At which temperature does catalase work best?
What is catalase activity? The reason being it is the perfect temperature for the enzyme. Table 1: Optimum working temperatures for commonly used enzymes in the lab. Upon hydrolysis by B-galactosidase, a yellow colored compound o-Nitrophenol ONP is formed. As the temperature increases so does the rate of enzyme activity. Nakazawa, "Comparative Researches in the Stabilities of Plant Catalase and Animal Catalase," Bulletin of the Institute for Chemical Research, Kyoto University, vol.
