What enzyme strips hydrogen atoms from organic molecules?
Cytochrome P450 enzymes are known to strip hydrogen atoms from organic molecules as part of metabolic processes, such as drug metabolism.
What gas is produces from mixing hydrochloric acid and magnesium strips?
Hydrogen gas is produced when hydrochloric acid reacts with magnesium strips. The chemical equation for this reaction is: 2HCl + Mg -> MgCl2 + H2.
What are the ingredients in the Crest Whitening Strips?
Crest Whitening Strips are used as a popular alternative for whitening teeth. The ingredients include: Water, Glycerine, Hydrogen Peroxide, Carbon 956, Sodium Hydroxide and Sodium Saccharine.
What are some potential side effects of using Crest White Strips?
Crest White Strips can cause tooth sensitivity and gum irritation. If the user has sensitive skin, they can also irritate the hands. These strips contain hydrogen peroxide, and it may be better to start with equivalent products with lower concentrations to see whether they suit.
What is the best way to create hydrogen?
Mix Hydrochloric acid with strips of magnesium and catch the resulting gas using a balloon over a test tube
What experiment shows how pH affects enzymes?
Equipment: - Hydrogen Peroxide - Catalase - Equally sized paper slips (a small rectangle, 2 cm X 1 cm) - Tweezers - Beaker - Stopwatch -pH testing strips -Acids (lemon juice, vinegar, etc.) -Bases (milk, baking soda, ammonia etc.) For the control, take one of the paper slips, using the tweezers, and dip it into the catalase, then place the catalase covered slip at the bottom of a beaker filled about halfway with hydrogen peroxide. You cannot simply drop the slip into the beaker, you must stick the tweezers into the beaker so that they reach the bottom, and then release. When the catalase contacts the hydrogen peroxide the hydrogen peroxide will release oxygen as a reaction, these oxygen bubbles in the liquid will push the paper to the top. Start the stop watch precisely when the strip enters the hydrogen peroxide, to measure the rate of reaction, and stop it again when the slip reaches the top. And finally for the affect of pH on the enzyme, simply change the pH of the hydrogen peroxide adding an acid, or a base. Then, just rerun the experiment and it will be evident that the pH affects the rate of reaction. The pH of hydrogen peroxide is roughly 2, or in that region, so adding a base will speed up the reaction, because the pH optimum of catalase is around 7.
What would be a good enzyme lab for ib biology?
A good enzyme lab for IB Biology could involve investigating how factors such as temperature, substrate concentration, or pH affect the activity of an enzyme like amylase. Students could test the enzyme activity under different conditions using a spectrophotometer to measure changes in absorbance, or by observing changes in the rate of a reaction such as the breakdown of starch. This type of lab allows students to explore enzyme kinetics and understand the factors that influence enzyme activity.
Why have the lengths of the potato strips changed during osmosis?
The potato strips changed length during osmosis because water molecules moved across the semi-permeable membrane from an area of higher water concentration to an area of lower water concentration. This caused the cells in the potato strips to either gain or lose water, leading to changes in their size and length.
Why do pH test strips change color?
the pH strips change because of the leavels of acid. the scale goes from 1-14 1-6 are acids 7 is nutral and so forth but the leavls of what you are testing affect it. if anything is added to the substances will change there leavles. so the short answer is the acid content.
What makes plants give off oxygen for people o breathe in?
Plants use water to create sugar for itself and strips the hydrogen and gets rid of oxygen which we use
What is the price of veet wax strips?
the veet wax strips cost about £6 for 20 strips or 16 strips for about £4 in the uk thankyou
Does listerine whitening strips have penicillin?
No, Listerine whitening strips do not contain penicillin. They primarily consist of ingredients designed for teeth whitening and oral care, such as hydrogen peroxide and various flavoring agents. If you have concerns about allergies or specific ingredients, it's best to check the product label or consult with a healthcare professional.
