Enzymes carry the genetic instructions required for a cell to initiate metabolism.

Enzymes increase the rate of the chemical reactions carried out during metabolism.

Enzymes provide the chemical energy that is broken down and released during metabolism.

Enzymes store the chemical energy that is used to construct nucleic acids during metabolism.

The enzyme has become saturated

The temperature is too low

The enzyme has become denatured

it allows some materials to pass through

it allows nothing to enter the cell, only to leave

It only allows things into the cell and not out

it allows all materials to pass through

into the cell

out of the cell

in and out of the cell at an equal rate

ATP

mRNA

protein

lipid

ATP senses and adjusts the pH in the cellular environment.

ATP identifies and repairs weak components of cells and tissues.

ATP measures and provides heat to increase reaction rates in cells.

ATP captures and transfers energy released by the breakdown of glucose.

Photosynthesis is one of the final steps in cellular respiration.

Photosynthesis provides the materials that fuel cellular respiration.

Photosynthesis absorbs excess energy produced by cellular respiration.

Photosynthesis absorbs materials that are catalyzed during cellular respiration.

DNA and a protein mix together to produce purple flowers.

Proteins stop the DNA from keeping the flower petals white.

DNA codes for a protein that makes pigments so the flower appears purple.

A pigment protein makes DNA, which causes the flower to appear purple.

meiosis, which produces body cells.

  Gene sequences that are identical are replicated and added to the homologous chromosome.

Sections of DNA between nonhomologous chromosomes are exchanged, decreasing genetic diversity.

  Segments of homologous chromosomes are exchanged, resulting in cells that will be genetically different.

  The traits from two sections of the same DNA strand are altered, resulting in the production of a new species.
