Hope it helped,
Happy homework/ study/ exam!
Answer: Option B
The enzyme has changed shape because of high temperature.
Explanation:
Enzymes are biological catalysts in living organisms that speed up the rate of chemical reactions.
High temperature changes the shape of enzymes.
Increase or high temperature lead to decrease in enzymes activities. This is due to enzyme protein been denatures by high temperature which is the breaking of molecular bonds within the enzyme protein. When the enzymes bonds are broken, the shape of the enzymes changes and they no longer act as catalysts.
Answer:
The information carried by DNA is incorporated in a code specified by the: specific nucleotide sequence of the DNA molecule. The enzyme DNA ligase is responsible for: linking short DNA segments.
Explanation:
Note that Facilitated diffusion , Active transport and Osmosis are three different ways of transporting substances across the cell surface membrane.
Facilitated diffusion is the movement of a substance from high to low concentration , similar to simple diffusion , but due to the complexity of the cell surface membrane , polar molecules and ions cannot just pass like that , so they pass through specific carrier and channel proteins in the cell surface membrane and so we call it facilitated diffusion.
For Active transport , it's the movement from low to high concentraion using energy from ATP
For Osmosis , it's totally different . You only name osmosis when its all about water . Its the net movement of water from high water potential to low water potential through partially permeable membrane .
If you're doing AS , you'll be familiar with Endosmosis and Exosmosis.
