Which structure forms as DNA unwinds? A. a special marker B. a complementary base C. a replication bubble D. a double helix
kozerog [31]

A replication bubble forms as the DNA unwinds.

Option C  

<u>Explanation</u>:  

Replication bubble is the space where the strands of double helical DNA structure are separated with the help of DNA helicase. The strands of the double helical DNA are still in the helix form on the both end of the unwinded DNA stand which gives this region an appearance of a bubble.

DNA unwinding is the first step in replication or transcription of the DNA molecule. DNA helicase separates the two types of "DNA" that are connected by hydrogen bonds with the help of ATP hydrolysis.

How many electrons are transferred in the ionic bond between sodium and chlorine in NaCl
Tpy6a [65]

One electron is transferred in the ionic bond because sodium needs to lose one electron and chlorine needs to gain one electron to have a full energy shell, which is the ultimate goal in any bond.

g Identify the statements that accurately describe how hydrogen ion concentration relates to energy production in oxidative phos
masha68 [24]

Answer:

- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.  

- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.  

- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.

Explanation:

Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.
