Starch + amylase). Poured contents of each beaker into its respective fermentation tube‚ ensuring the tail portion of the tube was filled with liquid. Placed tubes in an incubator at 37 degrees‚ measuring distance between tip of tube tail to fluid level at 20‚ 40‚ and 60 minute intervals. Calculated gas volume using this distance along with radius of tube tail. o Why is alcohol fermentation needed in yeast to carry out glycolysis In an environment absent of oxygen‚ yeast undergoes alcohol fermentation

exposed to light‚ over time‚ reorganization of the plastid membranes occur and all the required enzymes and proteins needed for photosynthesis appear. So undetectable levels of these proteins suddenly appear and become the most abundant in leaves with the presence of light. The increase of these enzymes are due to increased levels of their corresponding mRNA. Here’s a funny picture of a plant getting ripped. Let’s just assume he’s under light. Enzymes that are associated with growth in maize that

the test fair we will control the variables by measuring each variable out. Our controlled variables are: Number of cress seeds in each petri dish (15 each) Water absorbed by cotton wool (10ml) The location of the petri-dishes are at the same level and are both the same distance from the window. – this keeps the light source‚ the temperature and the supply of CO2 and O2 exposed to the plant the same. The room temperature fluctuates‚ but both plants experience the same temperatures making the
