Active transport

Active transport is the movement of a substance from low concentration to high concentration
(against its concentration gradient)

1

What is aerobic respiration

Process of producing cellular energy involving oxygen

2

What does aerobic respiration produce how many

Roughly 36 ATP

3

Where does aerobic respiration occur

The mitochondria

4

What is the first step in aerobic respiration

Glycolysis

5

What is the second step in aerobic respiration

Citric acid cycle

6

Is the third process in aerobic respiration

Electron transport system

7

What is aerobic respiration used for

Working your muscles, growth and repair of cells, building a larger molecules from smaller ones, allowing chemicals are reactions to take place, absorbing molecules and active transport, keeping your body temperature constant, sending messages along or's

8

Define anaerobic respiration

A form of respiration using electronic transports other than oxygen

9

Which cells use anaerobic respiration

Mostly in prokaryotes

10

What are the stages of anaerobic respiration

Glycolysis, Krebs cycle, electron transport chain

11

Product of anaerobic respiration

Carbon dioxide, ATP

12

Where is anaerobic respiration located

Mitochondria

13

What is ATP

ATP is considered to be the energy currency of life: high-energy molecule that stores the energy we need to do just about everything we do

14

Where is ATP synthesized

Mitochondria

15

Is the process by which the ATP is synthesized

Glycolysis

16

What is ADP

ADP is an ingredient for DNA. It is converted to ATP to release and store energy

17

Define chemosynthesis

In places in the world such as the seafloor where son cannot provide energy chemosynthesis is the process by which animals on the seafloor obtain energy through chemicals.

18

Define concentration gradient

The movement of high concentration to low concentration- kind of like diffusion

19

Define electron transport chain

Series of enzymes embedded in the membrane takes the electron carriers electrons and uses their energy for pumping protons increasing protein concentration

20

Define endocytosis

During endocytosisThe cell membrane folds into a pouch surrounding particles outside the cell.

21

What is formed to allow particles to move inside the cell during endocytosis

transport vesicle

22

Define exocytosis

The opposite of endocytosis. Particles are transported out of the cell. A vesicle containing Waste or cell products Ruth toward the cell membrane and fuses with it as the contents inside the vesicle are secreted

23

Defined facilitated diffusion

Also known as passive transport, The movement of a substance from low concentration to high concentration

24

What is glycolysis

Glycolysis is the source of ATP
Is a series of reaction that breaks down sugars while producing ATP

25

When does glycolysis occur

The cell needs energy

26

Where does glycolysis occur

In the cytoplasm

27

Define hydrophilic

Having a tendency to mix with dissolve in or be wetted by water

28

Define hydrophobic

Tending to repel or fail to mix with water

29

What is a phospholipid made of

A Phosphate group and a lipid
