Q

What is aerobic respiration used for

A

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

Q

What is ATP

A

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

15
Q

Is the process by which the ATP is synthesized

A

Glycolysis

16
Q

What is ADP

A

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

17
Q

Define chemosynthesis

A

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
Q

Define concentration gradient

A

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

19
Q

Define electron transport chain

A

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

20
Q

Define endocytosis

A

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

21
Q

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

A

transport vesicle

22
Q

Define exocytosis

A

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
Q

Defined facilitated diffusion

A

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

24
Q

What is glycolysis

A

Glycolysis is the source of ATP

Is a series of reaction that breaks down sugars while producing ATP

25
Q

When does glycolysis occur

A

The cell needs energy

26
Q

Where does glycolysis occur

A

In the cytoplasm

27
Q

Define hydrophilic

A

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

28
Q

Define hydrophobic

A

Tending to repel or fail to mix with water

29
Q

What is a phospholipid made of

A

A Phosphate group and a lipid

30
Q

The head is

A

Hydrophilic

31
Q

The tail is

A

Hydrophobic

32
Q

Define semi permeable

A

Allowing some molecules to go through the membrane while others cannot

33
Q

The phospholipid bilayer forms the barrier between

A

The interior of the cell and the exterior

34
Q

What are two major types of transport

A

Passive transport and active transport

35
Q

What are the subtypes of passive transport

A

Die fusion, facilitated I fusion, and osmosis

36
Q

What are some types of active transport

A

Protein pumps, endocytosis, and exocytosis

37
Q

Why does endocytosis require energy and therefore is considered active transport

A

The Selmore sits shape around the particle and envelopes it this requires energy

38
Q

How do organisms perform cell respiration

A

Cells take the carbohydrates into their cytoplasm and through a complex series of metabolic processes they break down the carbohydrates and release the energy
