Carbohydrate Fermentation Testing Questions A. What is fermentation? It is a metabolic process that allows the production of ATP without need for oxygen B. Why is it important not to incubate the fermentation tubes beyond 24 hours? You may not get accurate results. Although sugar is the primary nutrient used‚ when a microbe runs out of it‚ protein or other nutrients will be attacked This causes changes in the color of the medium because of the pH indicator added to detect acid production. When proteins

Nectar contains a mixture of sugars such as sucrose and fructose. a) To which family of compounds to sucrose and fructose belong.1KU Glucose can be broken down to form alcohol in the presence of an enzyme. b) i. What is the chemical name for the alcohol produced.1KU ii. What is an enzyme?1KU iii. Give another example

the lowest as shown in Table 3. The seed raffinose concentration on the other hand had inconsistent results. The seed stachyose concentration also showed a reverse trend in fructose glucose and sucrose due to the fact that seed stachyose concentration was seen in the WS-B crops. There was a good response in glucose and fructose in regard to the B application in both the well watered and the water stressed crops. Seed natural abundance δ15N and δ13C isotopes The results obtained showed that the foliar

The main objective of this lab is to see if the rate of cellular respiration will be affected if we change the food source from glucose to three different experimental variables (fructose‚ sucrose‚ lactose). Cellular Respiration is a process that generates ATP and it involves the complete breakdown of glucose to carbon dioxide and water. Carbohydrates‚ fats‚ and proteins can all be used as fuels in cellular respiration‚ but glucose is most commonly used as an example to examine the reactions and

Quek Lin Yuan (25) 212 Act 2 (To be graded) In Act 2 Scene 1‚ Portia is polite towards the Prince of Morocco and assures him that she would not discriminate against him for his dark complexion and he stood and equal chance. “Yourself‚ renowned prince‚ then stood as fair / As any comer I have look’d on yet / For my affection.” However‚ at the end of Scene 7‚ we later learn that Portia is rather racist‚ as she is prejudiced towards others of a very different skin colour‚ when she says “Let all of

Translocation of Organic Solutes Plants synthesize food materials by photosynthesis and store the same in the form of starch grains in the chloroplasts found in mesophyll cells. Then the found material is converted into simple sugars; then it is transported to regions where it is required – stem apex‚ young flower buds fruits and storage organs are the sites to which the organic food is translocated. The site of synthesis and the site of need are separated by time and space. The structures

photosynthesis a plant takes in carbon dioxide‚ water‚ and sunlight to produce its food and energy. The sun puts off wavelengths that allow plants to capture photons. To a plant photosynthesis is a process that produces sugars called glucose and fructose then the plant uses the sugars as food. To a human the process recycles carbon dioxide into oxygen for us to breath. The plants surroundings are where it acquires everything it needs for photosynthesis. It absorbs sunlight through its leaves as well
