How is energy stored in ATP?(1 point)
Responses

ADP loses one phosphate group, leaving it with more energy.
ADP loses one phosphate group, leaving it with more energy.

ADP is given a third phosphate group, which stores energy in the bond.
ADP is given a third phosphate group, which stores energy in the bond.

ADP is given energy from glucose until it has enough energy to become ATP.
ADP is given energy from glucose until it has enough energy to become ATP.

ADP loses its extra energy to ATP with the help of glucose.

The correct similarity between prokaryotic and eukaryotic cells is:

**Both prokaryotic and eukaryotic cells are filled with cytoplasm.**

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do. Also, not all prokaryotic and eukaryotic cells have a cell wall. Therefore, the statement about both types of cells being filled with cytoplasm is the only accurate similarity among the options provided.
Answered by GPT-4o mini
The correct answer is **cell wall**.

Plant cells have a rigid cell wall that provides structure and support, while animal cells do not have a cell wall. Chloroplasts are membrane-bound organelles found in plant cells, and both cytoplasm and mitochondria are present in both plant and animal cells.

The correct answer is **carbohydrates**.

Carbohydrates are the primary source of energy for cells and are utilized directly in cellular processes. While lipids also can store energy and proteins can be metabolized for energy, carbohydrates are specifically known for providing quick, accessible energy to cells.

The correct answer is **ADP is given a third phosphate group, which stores energy in the bond.**

ATP (adenosine triphosphate) is formed when adenosine diphosphate (ADP) gains an inorganic phosphate group, and the bond formed between the phosphate group and ADP stores energy. This energy can then be used by the cell for various biochemical processes.

The correct answer is **protein**.

The capsid is the protein coat that encloses and protects the viral genetic material, which can be either RNA or DNA. The capsid is made up of protein subunits called capsomers.

The correct answer is **The viral genome mutates very quickly.**

One of the reasons it's challenging to create a vaccine for the common cold is that the viruses that cause it, particularly rhinoviruses, have a high mutation rate. This rapid mutation allows them to evade the immune system, making it difficult for a vaccine to provide effective long-term protection.
