peroxide is broken down into what two less harmful
molecules in lab2?
a)oxygen and water
b)carbon dioxide and vinegar
c)water and syrup
d)oxygen and carbon dioxide
Option a is correct. Peroxide is broken down into oxygen and water. This reaction occurs in the presence of catalase enzyme.

Carbon dioxide and oxygen are molecules that can move freely across a plasma membrane. What determines the direction that carbon dioxide and oxygen molecules move? A. orientation of cholesterol in the plasma membrane B. concentration gradient across the plasma membrane C. confi guration of phospholipids in the plasma membrane D. location of receptors on the surface of the plasma membrane
The organic molecules of living organisms have a measurably lower ratio of carbon-13/carbon-12, two stable isotopes of carbon. The ratio of carbon 13/carbon-12 is higher in non-organic molecules. What does this tell us about the rise in CO2 in the atmosphere over the last century? O Carbon dioxide molecules containg carbon-13 are heavier and sink to the ocean depths, making them less available to organisms. O The source of CO2 rise in the atmosphere is definitely due to the burning...

Liquid heptane, C7H16, burns in oxygen gas to yield carbon dioxide and water. What is the minimum mass of oxygen required for the complete reaction of 25.5 mL of heptane? (density of heptane = 0.6838 g/mL) a)5.57 g b)8.14 g c)30.6 g d)61.3 g e)89.6 g
Why do we need hemoglobin to transport oxygen in the bloodstream, but no protein is required to transport carbon dioxide in the blood from the tissues to the lungs? A. carbon dioxide is hydrophilic, and can interact with water molecules in the blood, but oxygen cannot B. the bonds in carbon dioxide are nonpolar covalent bonds, but the bonds in oxygen are polar bonds C. carbon dioxide is surrounded by a shell of sodium ions in the bloodstream, but oxygen...
