Chemical energy

This is the energy stored in bonds between atoms in a molecule

ATP

The molecule that is the source of energy for cellular activities is called?

adenosine triphosphate

ATP stands for?

Two

ADP has ___ phosphate groups

Third

When a ___ phosphate group is added ADP becomes ATP.

Energy available

The 3rd Phosphate group will be added to ADP only when a cell has ______, and it will be removed when a cell needs energy for activities.

Second and third

The energy used for cellular activities is stored in the bonds between the ___& ___ phosphate groups

Active transport

The energy stored in ATP powers activities like ____, protein synthesis and muscle contraction.

Storing

The ATP molecule is great for transferring
energy but is not good for ___ large amounts of energy.

90

A single molecule of glucose (sugar) stores ___ times more energy than ATP.

Thylakoid

This is where the collection of light energy occurs.

Granum

This is a stack of photosynthetic membranes called thylakoids.

Chlorophyll

In the thylakoid, ____ and other pigments are organized.

Stroma

The space outside the thylakoid membranes is called?

Light independent reactions

Photosynthesis occurs in 2 stages: light dependent reactions & what?

Calvin cycle

Light independent reactions (that occur in the stroma) are also known as what?

Very energized

electrons become?

NADP+

The molecule used to carry these high energy
electrons is called?

NADPH

NADP+ accepts 2 high energy electrons and an H atom to become?
