olya-2409 [2.1K]

Answer:

True

Explanation:

Hox gene is responsible for giving form, shape or plan to body of an organism. These genes are set of transcription factor which specifies with in an organism’s embryo which part will form a specific organ of the body. These are found at the 3’ end of the DNA and are responsible for axial patterning. These genes are activated by regulatory genes and the proteins encoded at early stage expresses at the later stage.  

Hence, the given statement is true

Answer:

\boxed {\boxed {\sf C. \ They \ provide \ energy}}

Explanation:

This mitochondria is also called "the powerhouse of the cell" because it powers the metabolism, cellular processes, and chemical reactions in the body.

How does the mitochondria provide power?

  • They are the site of cellular respiration, a process that makes ATP molecules, or more specifically adenosine triphosphate molecules.
  • These molecules provide the useable <u>energy</u> needed for many different life processes, including protein synthesis.

Explain how enzymes work. Include the term activation energy and compare the two curves, explaining which is with the enzyme.
inysia [295]

One can draw the conclusion that enzyme lowers the activation energy of reactants, increasing the rates of reactions.

Reactants need to summon the activation energy in order to transform into products.

<h3>Include activation energy when explaining how enzymes function.</h3>

Biochemical catalysts include enzymes. The activation energy of reactions is reduced by catalysts. A reaction will proceed more quickly the lower its activation energy. As a result, enzymes reduce activation energy to speed up reactions.

Enzymes are catalysts, so they have an impact on activation energy by lowering the amount of activation energy required, enabling chemical reactions to occur or proceed more quickly. It has no impact on how much energy is released during the reaction.
