Question 10

The muscle cells of a very active organism would contain fewer mitochondria than those of a less active organism.

Accepted Answer

The muscle cells of a very active organism would contain more mitochondria than those of a less active organism because mitochondria are responsible for producing energy through aerobic respiration, which is essential for muscle activity during exercise. Therefore, the more active someone is, the more mitochondria their muscle cells need to produce energy.

Question 11

The mitochondria of plant cells contain thylakoids.

Accepted Answer

Thylakoids are actually found in chloroplasts, not mitochondria.

Question 12

Electrons gain energy as they move through the electron transport chain.

Accepted Answer

The answer of Electrons gain energy as they move through...

Question 13

The energy that is needed to produce the flash of a firefly originally comes from sunlight.

Accepted Answer

Fireflies, like many living organisms, obtain their energy from the sun through the process of photosynthesis. This energy is then stored in the form of chemical compounds, including the bioluminescent molecule luciferin, which produces the flash of light when oxidized in the presence of the enzyme luciferase. Therefore, the energy that produces the flash of a firefly ultimately comes from the sun.

Question 14

Cellular respiration is essentially the opposite of photosynthesis.

Accepted Answer

Photosynthesis converts light energy into chemical energy (glucose) while releasing oxygen, while cellular respiration uses oxygen to break down glucose and release energy (ATP) while producing carbon dioxide and water as waste products. The two processes are complementary and necessary in the cycling of energy and nutrients through ecosystems.

Question 15

You have shrunk to molecular size and find yourself in a mitochondrial chamber where protons are being pumped out of the chamber and across a membrane into another chamber.You are in the mitochondrion's ________.

Accepted Answer

The answer of You have shrunk to molecular size and...

Question 16

In C₄ plants,carbon fixation and the workings of rubisco are spatially separated.Carbon fixation occurs in the ________ cells,and then rubisco adds CO₂ to RuBP in ________ cells.

Accepted Answer

The answer of In C₄ plants,carbon fixation and the workings...

Question 17

Energy is used to force protons from the thylakoid space back into the stroma.

Accepted Answer

Energy is used to pump protons from the stroma into the thylakoid space, creating a proton gradient that drives ATP synthesis, not the other way around.

Question 18

During the Calvin cycle,the enzyme rubisco forms an unstable carbohydrate by combining CO₂ with a compound that contains ________ carbons.(Hint: The answer is a number. )

Accepted Answer

The answer of During the Calvin cycle,the enzyme rubisco forms...

Question 19

ATP synthase is a protein that participates in the redox reactions of the electron transport chain.

Accepted Answer

ATP synthase is a protein that synthesizes ATP from ADP and inorganic phosphate during oxidative phosphorylation and photophosphorylation, but it does not participate directly in the redox reactions of the electron transport chain.

Question 20

The series of chemical reactions that begins with rubisco adding oxygen to ribulose 1,5-bisphosphate (RuBP)and ends with the release of CO₂ is called ________.

Accepted Answer

The answer of The series of chemical reactions that begins...
