Answer:
Cold light means less than 20% of the light generates thermal radiation, or heat. Most bioluminescent organisms are found in the ocean. These bioluminescent marine species include fish, bacteria, and jellies. Some bioluminescent organisms, including fireflies and fungi, are found on land.

The student is wrong. Phosphorylation
cascade is important in cell signaling. Most cell signaling involves cyclic AMP (synthesized from
ATP). The cAMP activates Protein Kinases (PKA)
that phosphorylates protein
substrates involved in the signaling pathways
such as the GPCR. This helps in amplifying the initial signal.
Answer:
D) Enzymes make nonspontaneous reactions become spontaneous
Explanation:
Being spontaneous or non-spontaneous in nature depends on the difference in energy levels between substrates and products of the reactions. A reaction with substrates at higher energy levels than the products are spontaneous ones. On the other hand, the reactions wherein products have higher energy content than the substrates are non-spontaneous.
Enzymes do not change the energy levels of substrates and products, so, they can not make a non-spontaneous reaction to become a spontaneous one. Enzymes only lower down the activation energy for a reaction and thereby make the non-spontaneous reaction to occur at a faster rate.
