Which sequence accurately describes the flow of electrons in photosynthesis?
This sequence accurately describes the flow of electrons in photosynthesis: H2O → photosystem II → photosystem I → NADP
Which statement most accurately describes what happens to proteins that lack an ER signal sequence?
Proteins that lack an ER signal sequence are released into the cytosol.
Why is the sun light in the photosynthesis equation above the arrow?
Photosynthesis is a group of chemical reactions happening in sequence. The arrows represent the chemical reaction, where the reactants are on one side and the products are on the other. In the case of photosynthesis, the products of one reaction then react once again to form new products.
How is light energy processed in the light reaction of photosynthesis?
In simple terms, photosynthesis is the conversion of carbon dioxide (CO2) to carbohydrate (CH2O). To do this two things are needed: energy to drive the reaction and a source of hydrogen. The light reaction of photosynthesis produces two essential substances: ATP and NADPH. ATP provides the energy for the conversion of CO2 to CH2O, and NADPH provides the hydrogen. The light reaction depends on groups of chlorophyll molecules, called photosystems, absorbing light energy. The energy is used to eject high energy electrons from the chlorophyll. The energy in the electrons is then used to make ATP and NADPH. There are two photosystems, called photosystem I (PSI) and photosystem II (PSII), which work in sequence. (PSII comes before PSI in the sequence, but they were discovered and named in the reverse order!). PSII absorbs light and emits a high energy electron. The energetic electron then passes down a series of molecules, called an electron transport chain (ETC), releasing energy as it goes (you can visualise it as a ball bouncing down a set of stairs, losing energy as it falls). The energy released is used to make the energy carrier compound ATP. To replace the electrons lost from chlorophyll in PSII water (H2O) is split into hydrogen ions (H+), electrons (e-) and oxygen atoms (O): H2O = 2H+ + 2e- + O This is the source of the oxygen released by photosynthesis. The second photosystem, PSI, also absorbs light and emits a high energy electron from chlorophyll. The energy in this electron is used to drive the synthesis of NADPH from NADP+ ,hydrogen ions (H+) and electrons (e-): NADP+ + 2H+ + 2e- = NADPH + H+ The hydrogen ions needed for this come from the water which was split by PSII. The electrons lost from the chlorophyll in PSI are replaced by the electrons ejected from PSII. The result of all this is that light energy is converted into chemical energy in ATP, water is split to provide the hydrogen needed to make NADPH, and oxygen is released as a waste product. The ATP and NADPH are then used in the light independent reaction (the Calvin cycle) to concert carbon dioxide into carbohydrate.

Which sequence accurately describes the flow of electrons in photosynthesis?
This sequence accurately describes the flow of electrons in photosynthesis: H2O → photosystem II → photosystem I → NADP
What is the sequence of energy transformation during photosynthesis?
solar energy → potential energy stored in electrons and ATP → chemical energy stored in sugars
Where is Hamal on the main sequence?
Unfortunately, it is impossible to tell accurately where a star is on the main sequence.
What is the change in the sequence of bases in a DNA molecule most accurately referred to as?
The change in the DNA sequence is referred to as a mutation
The number which best completes the sequence below is 76.400 76.004.77.000 77.400?
We can't answer this accurately without knowing the sequence.
Which of the following statements does not accurately describe DNA?
A change in the nucleotide sequence of a gene
What is the most change in the sequence of bases in a DNA molecule is most accurately referred to?
A chromosomal replication
Which statement most accurately describes what happens to proteins that lack an ER signal sequence?
Proteins that lack an ER signal sequence are released into the cytosol.
Which explain the sequence of energy transformation during photosynthesis?
Light energy is transformed into chemical energy
What explains the sequence of energy transformations during photosynthesis?
Light energy is transformed into chemcial energy
What does the sequence in each period represent in relation to electrons?
The sequence in each period represents in relation to electrons is that as you look from left to right on the periodic table, you see a pattern; an increase of the atomic number. The number of electrons equals the number of protons, and the number of protons equals the atomic number.
What list accurately describes the sequence of events leading up to a chiefdom?
development of agriculture then job specialization then social stratification
