The process is ocurring by steps, starting with depolarization.
1- Na+ permeability > K+ permeability
2- Vm (membrane potential) approaches ENa+ (quilibrium potential for potassium)
3- K+ permeability > Na+ permeability
4- Vm (membrane potential) approaches EK+ (quilibrium potential for potassium)
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.
Answer:
The basic unit of life is a cell
Answer:
Ribosomes are found 'free' in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER. In a mammalian cell there can be as many as 10 million ribosomes. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome.
Explanation:
Hope this helps :D
c. Deoxyribose:RNA I think that's right I hope it is I'm sorry if I got it wrong
