What is the function of centrioles

Spindle apparatus and chromosome migration during mitosis

2

When does crenation occur in blood cells
Net( loss of water)

Hypertonic solution

3

When does hemolysis occur in blood cells.
(Net water gain)

Hypotonic solution

4

If trna has an ACG anticodon it could attach an________mRNA codon.

UGC

5

Diffusion

The movement of molecules (driven by kinetic energy) down a concentration gradient. High to low concentration.

6

Know the functions of the plasma membrane

Cell to cell interaction and recognition, enclosure for cellular contents including organelles and inclusions, selectively permeable...

7

Define and describe the generation of a membrane potential across the cell membrane

NaK pump producing the negative 90 millivolts across the plasma membrane

8

Passive transport

No energy input

9

Active transport

Solute pumping , depends on a carrier protein and energy

10

How are most larger molecule transported across the cell membrane in body cells?

Through active transfer

11

What properties attribute to the high specific heat and high surface tension of water?

Oxygen bond

12

The main component of cytosol

Water

13

Interpret mRNA and transfer RNA transcription events

Transcription occurs in the nucleus. Translation occurs in the cytoplasm

14

Second messengers

Intracellular signals which connect plasma membrane events to the internal metabolic machinery of the cell. Cyclic amp and ionic calcium

15

Lysosomes are organelles responsible for________

Intracellular digestion

16

What is the endomembrane system

Interactive organelles whose membranes are physically or functionally connected including the nuclear membrane, Golgi apparatus, endoplasmic reticulum, and plasma membrane

17

What is the function of mitochondria

ATP production
