A phosphate group is a part of a molecule (i.e. group) with the formula PO4.
Depending on the molecule it is part of it can be either inorganic phosphate or organic phosphate.
Phosphate groups are essential to many biochemical processes (e.g. ATP for energy storage, phosphorylation of DNA to inhibit/enable gene expression).
There are three phosphate groups in a molecule of adenosine triphosphate (ATP).
between phosphate groups
There are two phosphate groups in one molecule of ADP.
Two, as it now becomes adenosine diphosphate. when it has three it is adenosine triphosphate.
The DNA backbone, are made of alternating sugars and phosphate groups.
The correct answer is a. phosphate groups, guanine, and cytosine. Both DNA and RNA contain phosphate groups and the nitrogenous bases guanine and cytosine. However, DNA contains deoxyribose sugar, while RNA contains ribose sugar, which distinguishes the two.
Adenosine Triphosphate (ATP) has three Phosphate Groups, hence Triphosphate.
Between the phosphate groups
A negative charge, as do all phosphate groups.
There are three phosphate groups in an ATP molecule. Go on to Google images and type in ATP or adenosine triphosphate. Look for a picture that contains chemical symbols and lines. Now, commonly on the right hand side you will see the bulk of the picture. On the left should be a line with P's and O's in the middle of it. The P's of course are the phosphates. The P closest to the bulk is called the alpha phosphate. then working out you have the beta phosphate and then the gamma phosphate. The symbols for these phosphates are the Greek letters for Alpha, Beta, and Gamma.
The original molecule has two phosphate groups attached.
An ATP molecule has an extra phosphate group compared to an ADP molecule. This is because ATP has 3 phosphate groups as where ADP only has two phosphate groups.
