The DNA in a cell's nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well
spayn [35]

Answer:

PFK (protein): cytoplasm only (targeting pathway)

Insulin (protein): ER->Golgi->outside cell

Explanation:

Translation can be described as the mechanism by which a protein is produced through a mRNA.

If a particular protein is to function inside the same cell, then it doesn't need to get any modification so that it can travel outside the cell. Such type of proteins are translated on free cytoplasmic ribosomes and are released directly into the cytoplasm to perform their function. For example, PFK protein.

If a protein has to function outside the cell where it is produced, then it has to be modified. Such type or proteins are translated on the rough ER.  They are then modified in the Golgi complex and then transported outside the cell to the area where they have to function. For example, insulin.

How do I identify controls, independent and dependent variables
frosja888 [35]

Answer:

what you change vs what you are testing

Explanation:

The independent variable is the variable that you change. For example, if we were growing plants and wanted to see if more sun made them grow higher, you would change the amount of sun that each plant is exposed to.

The dependent variable is what you measure. This depends on the independent variable. So, in our plant experiment, the height of the plant is the dependent variable.

Control. The control is what stays the same. So in our plant experiment, the amount of water, type of plant, type of soil, and all of these things would stay the same to insure that the results are equal.

You affect the independent variable and the control and you test the dependent variable.

An amoeba uses a sugar molecule during metabolic activity. It loses energy to the environment as a result. The transformation of
34kurt

Answer:

Option B, chemical energy to thermal energy

Explanation:

All living organism feed on food that contains energy in the form of chemical energy. Once the food is intake and processed for fulfilling energy requirement of all metabolic processes with in a cell, the remaining energy is released as heat (thermal energy). Thus, an amoeba while consuming a sugar molecule converts chemical energy with in the sugar to thermal energy in the form of energy molecules.

Hence, option B is correct
