cells can transform into all cells come only from
different types. other cells.

Term
What type of reaction is necessary to produce a dipeptide from
individual amino acids
Give this one a try later!
glucogenesis dehydration reaction
, glycolysis hydrolysis

6 of 124
Term
This is a multiple answer question. Choose all that are correct.
Choosing incorrect questions will subtract from the grade on this
question. However, you cannot receive an negative grade on the
question.
Following is a list of examples of the forms of movement of
molecules across a membrane. Choose only those that require
energy input from the cell whose membrane is directly
involved.
Give this one a try later!
Acids increase the proportion of hydrogen ions (H+), and bases reduce the
proportion of H+
The 10 plots in each treatment
mitochondrion
chloroplast
nucleus
Insulin starts out in a vesicle inside a beta cell of the pancreas. When
blood sugar level rises the vesicle moves to the cell membrane and fuses
with the cell membrane.
The cell uses a sodium-potassium pump to create a high concentration
of sodium ions outside the cell.
