Answer:

ATP

Explanation:

Glycolysis (from the Greek glykos, sugar, and lysis, breaks down) is an anaerobic process, that is, without the presence of oxygen, which causes the degradation of glucose (C6H12O6). In this metabolic pathway, which occurs in the cytoplasm of the cells of all living beings, the formation of pyruvic acid (C3H4O3) and ATP molecules occurs. For this reason we can say that ATP is the correct answer to your question.

The unstable glucose molecule, when broken, forms two molecules of pyruvic acid and generates four molecules of ATP. As phosphates from two ATP molecules are used at the beginning of the process, the net balance is two molecules.

Answer:

  • Protozoans → would not have survived because they have no way to produce their own food → Heterotrophs
  • Algae → would have survived without this food source → Heterotrophs

Explanation:

The protist kingdom is composed of two main groups.  The principal difference between them is that algae can produce their own food, while protozoans need to ingest other organisms or organic molecules to survive.

  • Algaes are autotroph
  • Protozoans are heterotroph

<u>Protozoans</u>:

Microscopic unicellular organisms, eukaryotic and heterotrophs -predators or detritivores-. Most of them are aquatic free-living organisms, but some species are parasites. They feed on<u> bacteria</u>, other organic wastes, and other microscopic organisms. The phagocytosis process is normally used to ingest the food, invaginating their cell membrane.  

<u>Algae</u>:

Eukaryotic micro- or macroscopic organisms. Autotroph and photosynthetic. They might be either unicellular or pluricellular. They use sunlight to synthesize organic matter from water, CO₂, and mineral salts. Unicellular ones can be free-living or associate with others to form colonies. They are part of the phytoplankton and are ingested by heterotrophic organisms. Pluricellular algae do not create real tissues but they compose a tale. The depth at which they inhabit depends on the pigments they produce. All of them inhabit fresh or sea waters.

Select the most accurate statement describing the basic function of the light reactions of photosynthesis. Select the most accur
S_A_V [24]

Answer:

The basic function of the light reactions of photosynthesis is the conversion of solar energy to chemical energy.

Explanation:

In photosynthesis, the light energy is captured by chlorophyll pigment which is present in the thylakoid membrane. Then this light energy is used split water which releases the electron that enters the electron transport chain. Then electrons move through several electron carriers and helps to generates NADPH and ATP.  

These NADPH and ATP are used in the Calvin cycle to fix the carbon into carbohydrates like glucose. Glucose molecules is then used by the plant to get energy source and to make structural components like cell wall. Therefore during photosynthesis solar energy is converted into chemical energy like glucose.

Which statement explains why oxygen molecules easily diffuse across a cell membrane while glucose molecules do not?
Artemon [7]
Oxygen molecules diffuse fast because the main gas in a cell in Carbon Dioxide its like if it was 99.9 percent carbon that .1 percent is oxygen and carbon dioxide being what it is. Automatically overrides the amount of oxygen. Basically it is nonpolar
