Answer:

The steps of light reactions in order:

1. Electrons move down the electron transport chain, releasing energy

2. ATP uses energy to add a phosphate to ADP forming ATP

3. Electrons from the electron transport chain close to photosystem II replace the elctrons lost in photosystem I

4. A protein in the electron transport chain, pumps H+ ions from the stroma into the thylakoid space

5. Electrons from Photosystem I become energized and escape photosystem I and move down the second electron transport chain.

6. Water is split to replace the electrons in photosystem II

7. H+ ions flow down the concentration gradient through a channel in ATP Synthase, releasing energy in the process

8. At the end of the electron transport chain, the energized electrons and an H+ ion are used to reduce NADP+ to NADPH

9. Light energy is transferred to a chlorophyll reaction center where electrons become energized.

10. Photosystem II receives photons in the form of light energy

11. Electrons move to an electron acceptor in the electron transport chain and electrons in photosystem II are replaced by the splitting of a water molecule

I am pretty sure I got that right! :)

Which reaction would you employ to build a disaccharide from two monomers of glucose?
GenaCL600 [577]

Answer:

D. dehydration synthesis

Explanation:

Dehydration means removing water, and synthesis means building or creating something. Therefore, the synthesis of dehydration is defined as removing water to build something. This process occurs by removing a molecule of -OH (hydroxyl group) and a molecule of -H to form H2O or water. This results in the covalent bonding of two monomers (small molecules) to form a polymer (larger molecule).

Dehydration synthesis uses condensation in the process and when this continues for a long period of time, a long and complex chain is formed, such as those of disaccharide or polysaccharides. It is also responsible for storing excess glucose molecules as well as larger polysaccharides such as starch and glycogen.

What are antibiotics and when can they not be used
miv72 [106K]

Answer:

An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. Antibiotics DO NOT work on viruses, such as those that cause: Colds and runny noses, even if the mucus is thick, yellow, or green. Most sore throats (except strep throat) Flu.

How can fertilizer use be detrimental to the environment? a. It can enter waterways, causing them to accumulate an excess of nut
yan [13]

Answer:  d. All the above

Fertilizers can be deterimental to the environment. Excess use of fertilizers will result in eutrophication in the water body. Water body being more enriched with nutrients will result in excessive growth of aquatic plants. This also result in algal bloom in which algae grows on the surface of water body because of this atmospheric oxygen not able to reach the aquatic plants, hence results in oxygen depletion.
