Answers

Water would flow into them because they are hypotonic to the external environment

1. A cell cannot be subdivided into smaller units that maintain the living state- This is true.

2. The organism is a eukaryote, because it has a cell membrane, a cytoplasm, and DNA.

3. Nucleus, chromatin

4. Water would flow out of them because they are hypertonic to the external environment.

5. Because water provides electrons

6. None

7. ATP and NADPH

8. Glycolysis, pyruvate oxidation, Krebs cycle, electron transport.

9. Eighteen times more ATP is formed during aerobic respiration than during anaerobic respiration.

10. Glucose.

6CO2 + 6H20 + sunlight = C6H12O6 + 6O2 + ATP

D 100%

Explanation:

Substrate-level phosphorylation account for all the ATP produced during glycolysis. 2 ATP was expended while 4 ATP was produced with 2 NADH leaving net ATP of 2 produced from the Substrate-level phosphorylation

Question 1: the right answer is B.


The cell is the smallest basic structural and functional unit of all living things. There is a wide variety of living cells that differ in size, shape, function, behavior, and association, but they all describe the same basic model.


Question 2: the right answer is C.
The scientist made a mistake when it classifies it as a prokaryotic cell.

In a general sense, the term eukaryotic refers to all unicellular or multicellular organisms whose cells are called "eukaryotic". They have a nucleus and organelles (endoplasmic reticulum, Golgi apparatus, various plastids, mitochondria, etc.) delimited by membranes.

Eukaryotes are distinguished from prokaryotes (such as bacteria) which, for their part, are devoid of these structures. But what really differentiates eukaryotes from prokaryotes is the presence or absence of a nucleus.


Question 3: The right answer is A.


In eukaryotic cells, the genetic material is organized into a complex structure of DNA and protein located in the nucleus. This structure has been called chromatin.


Question 4: The right answer is C.


Some organisms have evolved into complex methods to circumvent hypotonia. For example, salt water is hypertonic for the fish that live there. They need a large area for their gills to come into contact with seawater, to facilitate gas exchange, so they can lose water by osmosis to the sea from the cells of their gills.


Question 5: the right answer is B.


The emission of a molecule of O2 requires the oxidation of 2 molecules of H2O; there are 4 electrons transferred.

2 H2O > O2 + 4 H + + 4 e-


Question 6: The right answer is D. None.


The carbon cycle is linked to photosynthesis. During photosynthesis, plants (that contains chlorophyll) turn carbon dioxide and water into carbohydrates (such as glucose), under the action of sunlight (away from the light that will not be able to happen).


Question 7: The right answer is B.


In the Calvin cycle, atmospheric CO2 is bound to organic compounds such as ribulose-1,5-bisphosphate. The formed compounds are then reduced and converted, for example, to glucose using NADPH and ATP formed as a result of the light-dependent reactions.


Question 8: The right answer is C.


The purpose of glycolysis is to provide molecules of pyruvates, which then go between oxidized to give acetyl CoA, which will enter the Krebs cycle, and generate electrons transporter such as FADH2 and NADH, H +, which will participate in the chain of electron transport.


Question 9: The right answer is D.


The degradation reaction of glucose to release ATP are as follows:

in aerobic environment: C6H12O6 + 6O2 → 6CO2 + 6H2O + 36 ATP + heat

in anaerobic environment: C6H12O6 → CO2 + organic residue + 2 ATP + heat


Question 10: The right answer is D. Glucose


Glucose (from grapes) is the source of carbon to produce wine by turning it into ethanol.

The correct answer is: Eighteen times more ATP is formed during aerobic respiration than during anaerobic respiration.

Explanation:

During aerobic respiration 36 ATP are formed. In contrast, in anaerobic respiration (lactic and alcoholic fermentation) only 2 ATP, obtaining energy from pyruvate during glycolysis.

The correct option is D. Eighteen times more ATP is formed during aerobic respiration than during anaerobic respiration.

Explanation:

Aerobic respiration can be described as the process of respiration taking place in the presence of oxygen. This process makes a lot more energy as compared to anaerobic respiration.

Anaerobic respiration can be described as the process of respiration taking place in the absence of oxygen. This process is one of the earliest reactions that occurred in organisms since the formation of life.

The process of aerobic respiration releases 38 ATP per glucose whereas the process of anaerobic respiration releases 2 ATP molecules per glucose. Hence, the ATP formed during aerobic respiration is approx 18 times more than the anaerobic respiration.

Aerobic respiration: can only be undergo if oxygen is present
Steps: Glycolysis, Krebs cycle, & Electron Transport Chain
Anaerobic respiration: no oxygen present need
Steps: Glycolysis, then either alcoholic or Lactic Acid
Things in Common: both do Glycolysis.
Hope that helps!
In aerobic respiration one glucose molecule generates 36 atp molecules while in anaerobic respiration one glucose molecule generates only 2 atp molecules.
