How might a substrate of the citric acid cycle block respiration when it is present in great excess

Biology
1 answer:
murzikaleks [220]3 years ago
4 0
The substrate of the citric acid cycle which can block respiration when it is present in excess is MALONATE. Malonate inhibits respiration by competing with succinate dehydrogenase for its acitve site. Malonate binds to the active site without reacting, thus competing with succinate. This disrupts the cellular respiration in the cell.

The Calvin cycle is considered light-independent because it can occur in darkness. However, most often the Calvin cycle takes pl
GarryVolchara [31]

Answer:

C) The Calvin cycle requires ATP and NADPH, which require sunlight to be produced

Explanation:

The light-dependent phase of photosynthesis includes the photolysis of water molecules. The released electrons are passed to PSII to PSI via electron carriers and finally to NADP+ to reduce it into NADPH.

Transfer of electrons via electron carriers also generates the proton concentration gradient which in turn drives ATP synthesis. ATP and NADPH formed during light reactions are used in the Calvin cycle as an energy source and electron donor respectively.

Hence, to continue, the Calvin cycle requires the synthesis of ATP and NADPH in the presence of light.

Keith_Richards [23]
<span>Silicon dioxide forms the cell walls of diatoms. These diatoms are a group of algae. Phytoplanktons are the most common types of diatoms that are unicellular. These organisms can form colonies in the shapes of filaments or ribbons, fans, zigzags, and stars that are perfect for monitoring environmental conditions, particularly water quality in the past and present. </span>
