Answer:
Human Activitys.
Explanation
The goods we use, travel around the world very quickly, and they often carry uninvited species with them.
The cell is most likely prokaryotic because:
Prokaryotes lack membrane-bound organelles such as the nucleus due to which the DNA are seen throughout the cytoplasm.
Eukaryotes have membrane-bound organelles such as the nucleus. So for eukaryotes, the DNA will be present packed inside the nucleus instead of being dispersed in the cytoplasm.
Prokaryotes can either be autotrophic or heterotrophic depending on their mode of nutrition. Autotrophic prokaryotes can make organic molecules for a carbon dioxide source. On the other hand, heterotrophic prokaryotes can take carbon from organic compounds. Hence, the organism can be autotrophic or heterotrophic.
<u>Answ</u>er:
False
,Cellular respiration not is the oxygen dependent process through which food molecules are broken down and the energy released used to generate atp.
<u>Explanation</u>:
Glycolysis is the primary phase in the collapse of glucose to abstract energy for cellular metabolism. Almost every living organisms bring out glycolysis as step of their metabolism. The method does not use oxygen and is hence anaerobic. Glycolysis occurs in the cytoplasm of equally prokaryotic and eukaryotic cells. Glucose arrives into the heterotrophic cells in two ways.
1. Over secondary active movement in which the movement occurs against the glucose concentration gradient.
2. Over a cluster of vital proteins called GLUT proteins, also called as glucose movement proteins. These transporters helps in the simplified diffusion of glucose.
NOTE: the steps of the signal transduction pathway to be arranged is in the attached file.
Answer:
The correct signal transduction pathway in order from the releasing of glucagon into the blood to the promotion of glycogenolysis includes:
- Glucagon binds extracellulary to G- protein coupled receptor.
-G protein releases GDP and binds FTP
-Activated G protein activates adenylate (adenylate) cyclase.
-Adenylate cyclase converts ATP to cAMP.
-Cyclic AMP activates protein kinase A
- phosphorylase kinase phosphorylates glucogen phosphorylase, an enzyme needed for glycogenolysis.
Explanation:
As carbohydrates from food consumed is digested, it's end product, the glucose, is assimilated into the cells for energy production through the help of insulin in a process called glycolysis. Excess of glucose is stored in the liver as GLYCOGEN.
In cases where there is reduced sugar in the blood (hypoglycemic state) another pathway (known as glycogenolysis through
GLUCAGON hormone) is initiated to elevate the concentration of glucose in the blood.
It has less dense region and it is almost 3 dimensional.
