lower chemical reactions

lower activation energy

increase activation energy

they do nothing

What happens to an enzyme experiences conditions (tempurate & pH) outside its optimal range?

It slows down the reaction

It goes into a dormant state

It speeds up the reaction

It denatures

1

Enzymes the activation energy in order to _ a chemical reaction.

decrease; slow down

increase; slow down

increase; speed up

decrease; speed up

1

ATP is often called the “energy currency” of the cell.
Which statement best describes the purpose of ATP and where it is made?

ATP stores genetic information and is made in the nucleus

ATP provides energy for cell processes and is made mainly in the mitochondria

ATP builds proteins and is made in the ribosome

ATP transports oxygen and is made in the cell membrane

1

Which statement best describes biogenesis?

Life forms from nonliving matter under early Earth conditions

Life arises from preexisting living organisms

Life forms only in the presence of oxygen

Life begins inside hydrothermal vents

1

Which observation provides the strongest evidence for the endosymbiotic theory?

Mitochondria contain their own DNA and reproduce independently

Cells require oxygen for cellular respiration

Ribosomes produce proteins in all cells

The nucleus stores genetic information

1

Which statement best describes the autogenous theory?

Organelles formed from engulfed prokaryotic cells

Organelles developed from infoldings of the cell membrane

Life formed from nonliving chemicals in the ocean

RNA developed before DNA

1

Which statement correctly compares the endosymbiotic theory and the autogenous theory?

Both explain how life formed from nonliving matter

Both explain how eukaryotic cells developed internal structures

Only the autogenous theory involves bacteria

Only the endosymbiotic theory explains membrane formation
