Control center for the cells contains DNA

Front 10

Cytoplasm

Back 10

Jelly like substance found inside the cell

Front 11

Cell membrane

Back 11

Let's certain substances in and out of the cell transports materials into and out of the cell

Front 12

Passive transport or diffusion

Back 12

The movement of a molecule from an area of high concentration to an area of low concentration. No energy is used

Front 13

Active transport

Back 13

Movement of molecules from low concentration to high concentration. Uses energy from the form of ATP

Transport

Back 19

Involves the movement of materials inside the cell as well as the movement between parts of a multicellular organism

Exertion

Back 20

The removal of all waste products by the cell of the body

Front 21

Synthesis

Back 21

The making or building of large molecules from smaller ones

Front 22

Photosynthesis

Back 22

Is the process of storing the energy from the Sun in the chemical bonds of glucose. Organelle used in the process of chloroplast

Front 23

Cellular respiration

Back 23

Occurs in the mitochondria of all organisms both plants and cells

Front 24

Enzymes

Back 24

Special proteins that affect the rate of chemical reaction enzymes are catalysts used in digestion and synthesis.

Front 25

What can affect an enzyme ? ( list all three types)

Back 25

1. Shape lock and key model. If it's a wrong shape it will not work.

2. Temperature each enzyme works best at a specific temperature.

3. PH levels hm sign works best at a specific pH level
