The power to do work is

Energy

List four forms that energy can take (not kinetic or potential)

a. Light


b. Heat


c. Chemical Energy


d. Concentration Gradient

The Greenhouse Effect traps energy in Earth's atmosphere in the form of

Heat

The food we eat stores energy in the form of

Chemical Energy

The location on a molecule where energy is stored is the

Molecular Bond

ATP gives up one to become ADP.

Phosphate Group

help chemical reactions work, but are not used up in the process.

Enzymes

A molecule that takes electrons from another molecule is called an

oxidizing agent.

the particles which actually move from one molecule to another in energy transfer are the

electron particles.

When a molecule loses electrons to another molecule. This is called

oxidation.

When a molecule gains electrons from one another molecule. This is called

reduction.

The reason the ATP molecule has so much energy is because all the phosphate groups have a charge.

negative

Wite the short formula for cellular respiration:

Glucose (C6H12O6)) + O2 + ADP -->


H20 + CO2 + ATP

The three main steps in a cellular respiration are

1. glycolysis


2. Krebs cycle


3. Electron Transport Chain

In glycolysis, one molecule of glucose becomes two molecules of

Pyruvic Acid.

In what chemical form is glucose when it enters the Krebs Cycle?

Acetyl-CoA

In cellular respiration, the main electron carrier is the molecule

NADH.

Most of the ATP in aerobic respiration is produced during

Electron Transport Chain

The last electron acceptor in the electron transport chain is

oxygen.

The organelle where most of aerobic respiration takes place is the

mitochondria.

At the end of aerobic respiration, the oxygen we breathe in ends up in a molecule of

water.

the carbon atoms in the carbon dioxide gas we breathe out come from molecules of

glucose.

Oxygen gets into our cells, and carbon dioxide gets out, by the process of

diffusion.

What enzyme, in the inner membrane of the mitochondria, adds energy to the energy molecule?

ATP synthase

In aerobic respiration, the word "aerobic" means that is used.

oxygen

Which step in cellular respiration takes place in the cytosol?

Glycolysis

Which step in cellular respiration takes place in the inner compartment of the mitochondria?

Kreb Cycle

Which step in cellular respiration takes place in the inner membrane of the mitochondrion?

Electron Transport Chain

The ATP synthase molecule is driven by a concentration of

protons.

In cellular respiration, how man ATP are made during:


a. Glycolysis?


b. Krebs cycle?


Electron Transport Chain?

a. 2


b. 2


c. 32

How many ATP are used to start glycolysis?

2

How many ATP are produced with the energy carried by one NADH molecule?

3

Write the short formula for photosynthesis:

CO2 + H2O -->


Glucose + O2

In photosynthesis, plants take in energy in the form of

light energy.

The pores in the leaf of a plant that open and close to let CO2 in are

stomata.

The organelle where photosynthesis takes place is the

chloroplast.

The pigment that absorbs light energy and gives up electrons is

chlorophyll.

Photosystem II and Photosystem I are reactions.

light dependent

The light-independent step of photosynthesis is the

Calvin Cycle.

The main electron carrier in photosynthesis is

NADPH.

The enzyme rubisco "normally" binds with

CO2.

They oxygen released in photosynthesis comes from

water.

Light dependent reactions take place within the membrane.

thylakoid

Photosystem II receives from water.

electrons
