there aren't many enzymes in food, mainly in fruits, the enzymes in friuts are very similar to ptylin found in the mouth that help break down sugar, they do not need to be ingested before they activate, a proof of this is the apple test, buy an apple, take a bite and leave it without covering it for a few minutes, you'll notice that the bitten part starts turning yellowish brown because the enzymes in the apple are already breaking it down.
In summary, they do not need to be ingested before activation, and the major characteristic of an enzyme is that they do not change after they react with (breakdown) food, so they are in the same form before and after they finish breaking down the food.
When plates divide or separate it creates a divergent boundary.
Answer:
C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.
Explanation:
Plant withering refers to the virtual death of plant cells due to lack of food. During the light-dependent reactions of photosynthesis, ATP needed for the synthesis of sugar (food) is created in the thylakoid membrane of the CHLOROPLAST of plant cells.
In the light-dependent reaction, hydrogen ions (H+) builds up/accumulate in the thylakoid lumen to create an electrochemical or proton gradient i.e. a difference in the concentration of H+ ions across the membrane. The hydrogen ions passes through a protein complex called ATP synthase, which forms ATP from ADP (by adding phosphate group), from the energy generated by the electrochemical gradient formed as a result of hydrogen in (H+) build up.
Hence, a plant that possess leaky membrane due to the cold temperature will likely wither because H+ ions are not able to accumulate inside the thylakoid causing a proton gradient, so ATP synthase makes too little ATP.
Answer:
They have more of the Macro nutrients Fat and Protein
Explanation:
Protein and Fat amd Carbs make the three macros
Answer:
a. cytology
Explanation:
<em>Cytology is a branch of biology that deals with the study of the cell. The study of the cell include the anatomy (structure), physiology (function), chemistry (reactions), etc.</em>
Option b is incorrect. Genome is the total genetic component of a cell or an organism.
Option c is incorrect. Pathology is a branch of medical science that deals with the study and diagnosis of diseases.
Option d is incorrect. The nucleus is an organ within the cell that contains the bulk of the genetic components of the cell and hence, controls a lot of the cell's activities.
The correct option is a.
