Answer:
The IV is the food and the DV is how much mass they gained over 3 weeks with certain food.
Explanation:
The food is the independent variable while the mass is the dependent variable. The dependent variable is the variable that changes in response to changes in the independent variable. The independent variable is the variable that is deliberately altered to monitor its effects on the dependent variable.
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.
The lobe of the Cerebrum that is immediately posterior to
the central sulcus and that is involved in general sensory functions is the Parietal
lobe. The parietal lobe terminates posteriorly at the parieto-occipital sulcus,
laterally at the lateral sulcus, and anteriorly at the central sulcus.
Water is considered polar because of the overall charge is unevenly distributed
