In DNA synthesis, two reactions are coupled. One reaction is exergonic and releases energy that drives the other reaction, which is endergonic and requires energy input.  The endergonic  reaction is [b], and the exergonic reaction is [a]. (Hint: think logically – even if you don’t remember this, you can think it through.)

The primary function of the cell wall is to _______.

What is true of cells produced by mitosis?

Put the following events of the mitosis in the correct order from the event that happens earliest in mitosis to the event that happens latest in mitosis. chromosomes align at center of cell chromosomes start to condense nuclear envelope disintegrates nuclear envelope re-forms sister chromatids separate spindle attaches to chromosomes

During cellular respiration, O2 _____.

How does fermentation allow ATP production to continue?

Put the following steps of DNA replication in the correct order beginning with the start of DNA replication. an RNA primer is synthesized beginning at the origin of replication covalent bonds form between Okazaki fragments, sealing the gaps between pieces DNA nucleotides are added to the growing strand hydrogen bonds between the two strands are broken primers are replaced with deoxyribonucleotides proteins attach to single-stranded DNA to stabilize it and prevent hydrogen bonding Write your answer as the sequence of letters – for example, A, B, C, D, E, F (note that this is not the right answer).

Glycolysis of cellular respiration occurs in the [a]. The other stages of cellular respiration occur in the [b]. Photosynthesis occurs in the [c].

A chemical binds to the final protein in the electron transport chain and prevents it from accepting electrons. This would cause ATP production by ATP synthase to _______.

In oxidative phosphorylation, the movement of hydrogen ions down their gradient (from the intermembrane space to the mitochondrial matrix) is [b] and is coupled directly to [a].
