Answer 11

Different metabolic reactions

Question 12

Lysosomes contain hydraulic enzymes, which are important intracellular digestion. The recycling of the cells organic materials and program cell death.

Answer 12

Lysosomes

Question 13

Vacuoles have multiple roles, including storage and release of macro molecules and cellular waste products and plants and aids and retention of water for turgor pressure

Answer 13

Vaculoles

Question 14

The folding of the inner membrane does what

Answer 14

Increases surface area, which allows more ATP to be synthesized

Question 15

Answer 15

Thylakoids and stroma

Question 16

Thylakoids ar organized and stacks called

Answer 16

Grana

Question 17

Membranes contain what that compromise the photosystems

Answer 17

Chlorophyll, pigments and electron transport proteins

Question 18

What occurs in the grana?

Answer 18

Light dependent reactions of photosynthesis

Question 19

What is the fluid within the inner chloroplast and membrane outside the thylakoid?

Answer 19

Stroma

Question 20

What cycle reactions of photosynthesis occurring in the stroma

Answer 20

Calvin Benson cycle

Question 21

Reactions occur in the matrix of the mitochondria

Answer 21

Krebs cycle

Question 22

What occurs in the inner mitochondrial membrane?

Answer 22

Electron transport in ATP synthesis

Question 22

Organisms have evolved, highly efficient strategies to obtain nutrients and eliminate waste cells and organisms use specialized exchange surfaces to obtain and release molecules from or into the surrounding environment

Answer 22

Yeah

Question 23

As organisms increase in size their surface area to volume ratio decreases affecting properties rate of heat exchange with the environment

Question 24

More complex cellular structures are necessary to adequately exchange materials

Question 25

Cells increasing volume of the relative surface area decreases the demand for internal resources increases

Question 26

Limitations restrict cell size and shape. Smaller cells typically have higher surface area to volume ratio and more efficient exchange materials.

Question 27

Cells are the

Answer 27

Basic unit of life and make up all living things, come from pre-existing cells
