• enzyme

• substrate

• protein

Enzymes catalyze reactions by ___________ Activation Energy.

• increasing

• decreasing (lowering)

• protein

• stables

NGSS.HS-PS1-5

At high temperatures or a wrong PH enzyme activity declines because it:

• protein

• denatures (change it's shape)

• increase activation energy

• ions compounds

What kind of transport does not require energy? example, simple diffusion or facilitated diffusion.

• organic transport

• osmosis

• passive transport

• active transport

What is facilitated diffusion?

• Transport that uses protein channel to help move molecules across the membrane. 

• When molecules spread from High to Low concentration on their own. 

• When pressure pushes something through a membrane. 

• Movements of substances through a membrane. 

osmosis is water movement. What is an isotonic solution?

• Has a greater pressure 

• When the solution has less solute

• When the solution has more solute 

• When solutions are in equilibrium (balance)
