Answer:
a substituted derivative of purine, especially the bases adenine and guanine present in DNA.
a colorless crystalline compound with basic properties, forming uric acid on oxidation.
Answer: Mitochondria
Explanation:
This image represents the aerobic breakdown of glucose (respiration), this occurs in the mitochondria.
Hope this helps!
B, molecules in a solid are still yet with small vibrations
Answer:
they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes
Explanation:
G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.
Answer:
Glucose is quickly broken down by liver and muscle cells to provide energy, which demonstrates that its type of chemical bonds is related to its function.
