Cell Transport *** ENG

A protein pump is used in ​ (a)   transport to move substances ​ (b)   → ​ (c)   .​

• active
• Low
• High

Active transport is the movement of particles ​ (a)   the concentration gradient (​ (b)   to ​ (c)   ). It requires ​ (d)   (energy).​ ​ ​

• AGAINST
• low
• high
• ATP

AGAINST the concentration gradient is from ​ (a)   to ​ (b)   concentration.​

• low
• high

WITH the concentration gradient is from ​​ (a)   to ​ (b)   concentration.​

• high
• low

There are 3 forms of ​ (a)   transport. They do ​ (b)   require the use of ​ (c)   energy. They are: osmosis, diffusion and faciliated diffusion.​ ​

• passive
• not
• ATP

There are 3 forms of ​passive transport. They do ​ (a)   require the use of ​ATP energy. They are: ​ (b)   , ​ diffusion and ​ (c)   diffusion.​ ​

• not
• osmosis
• faciliated

Facilitated ​ (a)   is the movement of molecules across a membrane with the help of ​ (b)   . NO ​ (c)   is necessary.​ ​

• diffusion
• PROTEINS
• ENERGY

A protein channel is used in ​ (a)   transport (from ​ (b)   → ​ (c)   )

to move substances that are too ​ (d)   for diffusion.​ ​

• passive
• High
• Low
• large

​ (a)   transport is the movement of particles ​ (b)   energy, as in ​ (c)   and osmosis.​ ​

• Passive
• WITHOUT
• diffusion

Osmosis is the ​ (a)   of ​ (b)   across a membrane. NO ​ (c)   is necessary.​
