Label the figure below. Word bank: leading strand, lagging strand, DNA
Natalija [7]

Answer:

DNA can replicate itself because its two strands are complementary. This means that one strand can be used as a template to make the other strand. It happens right before cell division via mitosis or meiosis so that each new daughter cell can have a complete genome.

Before replication can start, the double strands of DNA need to separate from each other. An enzyme called DNA helicase breaks the hydrogen bonds that connect the two strands, allowing them to come apart.

The point where this unzipping starts is called an origin point. Eukaryotic DNA can have more than one origin point, but prokaryotes can only have one.

The points where DNA is currently unwinding are called replication forks.

Which of these statements are accurate? Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group fr
Agata [3.3K]

Answer:

A. The conformational shift that occurs when glucose, but not water, enters the active site prevents water from hydrolyzing ATP. True

B. Hexokinase consists of two domains, or lobes, that come together when glucose and the MgATP2–MgATP2– complex are bound. True  

C. Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. True

Explanation:

A. Hexokinase suffers and conformational changes by binding glucose in a reaction that prevents ATP hydrolysis.

B. Hexokinase is an enzyme with two domains that function by binding to the substrate (i.e., glucose). The region linking both protein domains is responsible for the catalytic activity.

C. Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. During the first stage of glycolysis, the hexokinase transfers one phosphorous group from magnesium-ATP (Mg-ATP) to one hexose molecule, such as fructose, mannose or glucose.

 

False statements:

- Most kinases require the presence of a monovalent metal ion cofactor to prevent ATP hydrolysis. False: In canonical kinases, conserved amino acids bind to divalent metal ions before the transference of the phosphate group to their substrates.

- Hexokinase is found in the mitochondrial membrane. False: Hexokinase is found in the cytosol.

- Hexokinase transfers the terminal phosphate of ATP to carbon 3 of glucose. False: Hexokinase catalyzes the transfer of the terminal phosphate ATP to form glucose 6-phosphate.

How do organisms interact with the living and<br> non-living elements of their environments?
IRINA_888 [86]

Answer:

How do organisms interact with the living and  non-living elements of their environments?

The interaction of living organisms with non-living organisms within an environment is called an ecosystem. Every living organism must interact with non-living organism in order to maintain a balanced ecosystem
