Biology

Question 1

what is active transport?

Answer 1

the movement across a semi-permeable membrane that requires energy input from the cell

Question 2

How does active transport work?

Answer 2

• active transport involves protein embedded in the phospholipid bilayer of the cell membrane.
• ## active transport cost energy as substances are moving from low concentration to high concentration

Question 3

when does active transport happen?

Answer 3

it happens when controlling how transport protein opens and closes to one side of the membrane to another.

Question 4

what is ATP?

Answer 4

The “battery” of the cell
is a phosphate groups is removed, and energy is used from that reaction to change the shape of the protein

Question 5

why does cell need to pump out of calcium?

Answer 5

• calcium is the signaling molecule
  -helps the the muscle contraction and relax

Question 6

what effects active transport?

Answer 6

• temperature
• concertation of ions/molecule that being transport
• ATP availability

Question 7

what is bulk transport?

Answer 7

the name of two process that move very large molecules, small amount of fluid or large particles

Question 8

what is exocytosis?

Answer 8

• a vesicel containing substance to be removed from the cells fuses with the cell membrane

Question 9

what does exocytosis carries out?

Answer 9

-large waste
-signaling proteins

Question 10

what is endocytosis?

Answer 10

part of the membrane folds in to form a vesicle inside, containing material that was outside the cell membrane

Question 11

what is phagocytosis?

Answer 11

cell eating
when the material being engulfed

Question 12

what is pincytosis?

Answer 12

cell drinking
water within soluble particles being engulfed

Question 13

what does endocytosis carry in?

Answer 13

-large molecules
-large material
-large amounts of water

Question 14

what does ATP stand for?

Answer 14

Adenosine triphosphate
“charged battery”
two high power bonds

Question 15

what does ADP stand for?

Answer 15

Adenosine diphosphate
“Battery with only partial charge left.”

Question 16

what does AMP stand for?

Answer 16

Adenosine monophosphate
“uncharged battery”

Question 17

what does ATP do?

Answer 17

the molecule that cell’s use for energy. is the energy “currency” when a muscle needs energy contact it “spends” converting into ADT

Question 18

what is hunger signal’s?

Answer 18

forms of AMP let the cells know when they are hungry
when these levels are high they know they need to eat more

Question 19

how does chemical reactions happen in the cell?

Answer 19

the chemical reactions need energy and they use the ATP as a battery to help power different chemical reactions.

Question 20

what is the ATP synthase the cell’s “water wheel” ?

Answer 20

hydrogen flow through ATP syathes like a water wheel that cause the top part if the ATP to rotate.
pockets open and close inside ATP is formed from ADP

Question 21

what is photosynthesis?

Answer 21

the process plants use to harvest the sun’s light energy and store as a chemical energy

Question 22

what are the parts of photosynthesis?

Answer 22

light energy from the sun, 6 co2 and 6 h20 go to chloroplast and 6 02 and 1c H12 O6 glucose

Question 23

what is aerobic cellular respiration?

Answer 23

When cell’s break down sugar and harvest the store energy from into a usable energy from

Question 24

what are the 3 phase of aerobic respiration?

Answer 24

glycolysis
kerbs cycle
oxidative phosphorylation

Question 25

where does aerobic cellular respiration phase take place?

Answer 25

mitochondria

Question 26

what are the parts in cellular respiration?

Answer 26

6 glucose + oxygen -6 carbon dioxide + 6water

34 ADP + 36p- 36 ATP
