yuradex [85]

Answer:

The chemical compound that breaks down the insects is most likely <u>enzymes.</u>

Explanation:

Venus flytraps and sundews are carnivorous- they consume insects to absorb nutrients via digestion. During absorption,  their cells take up molecules synthesized via the breakdown of macromolecules like carbohydrates and proteins. When regions of the plant come into contact with insects, these plants recognize specific macromolecules like chitin, they increase the production of digestive enzymes.

Forming digestive liquid enzymes are specialized proteins that function as biological catalysts to speed up reactions. They act on substrates, which can bind to specific regions of the enzyme, called the active site. Once bound in the presence of highly specific temperature and pH, enzymes increase the rate of a reaction over time.

Common enzymes found in their digestive secretions include chitinases, phosphatases, amylases, and proteinases.

Describe how oxygen gas (O2) is produced during photosynthesis. Include the specific structures in the plant where the reaction
Dmitriy789 [7]

Answer:

See the answer below

Explanation:

Oxygen gas is produced during photosynthesis by photolysis of water in the chloroplasts of algae and green plants and in the thylakoid of cyanobacteria. The chlorophyll of photosystem II absorbs light energy which leads to the excitation and knocking out of an electron within the photosystem.

The energy released as a result of returning the electrons to the ground state in an acceptor molecule is used in splitting water molecules into hydrogen and oxygen. The electron released from the splitting of water replaces the one knocked out from the photosystem II while oxygen atoms from two water molecules combine to form diatomic oxygen which is later released as oxygen gas.

The whole process of photolysis of water and the release of oxygen gas happens during the light-dependent reaction of photosynthesis.
