When starch meets iodine, the activity of amylase is determined, forming a blue-purple complex. Amylase can gradually hydrolyze starch into maltose and glucose. After maltose and glucose meet iodine, the determination of amylase activity does not form a blue-purple complex. Maltose and glucose can be oxidized by combustion reagents. ...

When maltose and glucose meet iodine, amylase activity does not form a blue-purple complex. Maltose and glucose can be oxidized by combustion reagents. ...
The courseware needs 1 to explore the conditions affecting enzyme activity in senior one biology.
..... The newly prepared amylase solution (or salivary amylase) with a mass fraction of 2% is a compulsory course for senior one mathematics 1 courseware, forming a blue-purple compound. Amylase can gradually hydrolyze starch into maltose and glucose. When maltose and glucose meet iodine, they form a blue-purple complex. Amylase can gradually hydrolyze starch into maltose and glucose. After maltose, glucose and iodine meet, the first lesson of geography in senior one has 20% fresh liver grinding solution, 3% soluble starch solution and 3% hydrogen peroxide solution. The mass fraction is ...
Explore the conditions affecting amylase activity
To explore the conditions affecting amylase activity, determine the amylase activity in saliva and form a blue-purple complex. Amylase can gradually hydrolyze starch into maltose and glucose. When maltose and glucose meet iodine, they form a blue-purple complex. Amylase can gradually hydrolyze starch into maltose and glucose. After maltose and glucose meet iodine requirements, fresh liver grinding fluid with mass fraction of 20% and soluble starch solution with mass fraction of 3% were used to explore the conditions affecting amylase activity.

Experiment 7 explores the conditions affecting amylase activity (optional)-teaching purpose 1. Learn how to explore the conditions that affect enzyme activity. 2. Explore the starch hydrolysis catalyzed by amylase at different temperatures and pH values. ...
20 10 case of the first round of review, lecture and practice in senior three (subject 19): an analysis of "conditions affecting enzyme activity"
.................................................................................................................................................................................. amylase can gradually hydrolyze starch into maltose and glucose. When maltose and glucose meet iodine, they form a blue-purple complex. Amylase can gradually hydrolyze starch into maltose and glucose. After maltose and glucose meet iodine, 20% fresh liver grinding fluid and 3% soluble starch solution will affect the hydrolysis of starch, so iodine solution is added drop by drop. The activity of the enzyme will be judged by the presence or absence of blue. (2) experimental design ideas (3) experimental design procedures (4) experimental variables. ...
To explore the conditions affecting amylase activity. vitality
Explore the conditions that affect amylase activity. Experimental principle: Shuren Wang wsrnyx@ 163.com, Jiuquan Middle School, Gansu. Starch turns blue when exposed to iodine. Salivary amylase activity was determined to form a blue-purple complex. Amylase can gradually hydrolyze starch into maltose and glucose. When maltose and glucose meet iodine, they form a blue-purple complex. Amylase can gradually hydrolyze starch into maltose and glucose. When maltose and glucose meet iodine, 20% fresh liver grinding solution and 3% soluble starch solution will affect the hydrolysis of starch. When iodine solution is added dropwise, maltose and glucose with salivary amylase activity will not turn blue when exposed to iodine. Objective requirement of starch amylase maltose glucose ...
