In general, reaction rates increase as the temperature increases. This is true for enzymatic reactions, up to a point. Describe the graph below and provide a reason for whythe rate of enzymatic reactions stop increasing.Model 2: Effect of temperature on enzyme reaction ratesReaction RateStoob van WAH)01020304040Temperature (°C)505060

Using this graph, what can be determined about the effect of enzyme concentration on the initial rate of the reaction and on the amount of product formed?
Use the reaction energy diagram above to answer the following questions.
[RCOOH], M [R’OH], M [HA], M Initial Rate, M-min 23. 0.35 0.35 0.50 4.60 0.62 0.35 0.50 8.14 0.35 0.81 0.50 10.6 0.35 0.50 0.75 9.84 Rate = k[RCOOH][R'OH] Rate = k[RCOOH][R'OH][HA] Rate = k[RCOOR']/{[RCOOH][R'OH]} Rate = k[R'OH] Rate = k[RCOOH] 26. The initial reaction rate for the reaction in question 23 can be followed spectrophotometrically by quenching the reaction and determining the amount of R'OH left by its reaction with the dichromate ion, Cr20-2-. Write a balanced equation for the reaction of Cr20,2- with R'OH in acid solution. For simplicity, you may assume R' is an ethyl group (CH3CH2) and the products of the reaction are Cr3+ and CH3COOH.

How is this reaction sequence regulated? CO2(g) + H2O(l) ⟷ H2CO3(aq) H2CO3(aq) ⟷ H+1(aq) + HCO3-1(aq) Group of answer choices Breathing controls carbon dioxide concentration and carbonic anhydrase catalyzes the reaction to lower the activation energy. Ingestion of nutrients controls carbon dioxide concentration and carbonic anhydrase catalyzes the reaction to lower the activation energy. Breathing controls carbon dioxide concentration and carbonic anhydrase catalyzes the reaction to increase the activation energy. Metabolism controls carbon dioxide concentration and carbonic anhydrase catalyzes the reaction to increase the activation energy. Ingestion of nutrients controls carbon dioxide concentration and carbonic anhydrase catalyzes the reaction to increase the activation energy.
Our body obtains energy from the combustion of glucose. During this process, glycerate is transformed first into pyruvate. This reaction has an activation energy close to 44 kJ. Estimate how many times faster this reaction is when someone has a high fever close to 106 F (41 oC) compared to its rate at normal body temperature (98.6 F; 37 oC). Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a b с d 31% faster 11% faster 24% faster 259% faster Your answer
What can contamination of reagents leads to? Unreliable results Reliable results Reproducible results Good results Catalase is the enzyme found in potatoes and It decomposes hydrogen peroxide (H202) to form water and oxygen gas. H202 + catalase - ----> H2O + 02 +E. The reaction is maintained at temperature 40 degree Celsius and there was a formation of bubbles. Based on the enzymatic reaction given, What do you think is the substance responsible for the formation of bubbles? Oxygen gas Hydrogen gas no reaction, because the enzyme catalase will be deactivated no reaction, because the enzyme catalase will be denatured Other: Based on the Fehling's test video, do you think the sugars ribose (in RNA) and the deoxyribose (in DNA) will both form a positive result (red precipitate) No Yes
