16
Q

Active tranport

A

ATP driven, requires energy, low to high

17
Q

Types of active transport

A

Primary active transport and Secondary active transport

18
Q

Primary Active Transport

A

directly use energy

19
Q

Example of primary active transport

A

sodium potassium pump moves sodium ion, using the energy of ATP hydrolysis to establish a concentration gradient

20
Q

Secondary Active Transport

A

does not directly use ATP, relies on the energy stored in the form of ion gradient created by the PAT

21
Q

Bulk transport is also known as

A

Vesicle transport

22
Q

Bulk transport

A

movement of large quantities of material into or out of cells using membrane-bound vesicle

23
Q

Types of bulk transport

A

Endocytosis and exocytosis

24
Q

Endocytosis

A

engulf extracellular material/going inside

25
Q

Types of endocytosis

A

Phagocytosis, Pinocytosis, Receptor

26
Q

Cell eating

A

Phagocytosis

27
Q

Cell drinking

A

Pinocytosis

28
Q

Receptor

A

takes in molecules that bind to receptors on the cell surface

29
Q

Exocytosis

A

Expel extracellular materials into extracellular space/going outside

30
Q

Which specimen diffused father?

A

Potassium permanganate, due to its smaller molecular size

31
Q

How does the molecular weight of congo red, safranin and potassium permanganate
affect the rate of diffusion?

A

If a molecule has a lower molecular weight, less effort to move through. If larger molecular weight, more resistance due to its size and slow down the rate of diffusion
