how are cellular respiration and photosynthesis almost opposite processes

photosynthesis uses carbon dioxide, and cellular respiration produces it.

What is a ATP molecule made of

Adenine, Ribose, Phosphate.

Is ATP discarded by the cell as waste

No

What is released during cellular respiration

Energy (In the form of ATP) Carbon Dioxide and Water.

What are the reactants in the equation for cellular respiration

Glucose and Oxygen

Cellular respiration is called an aerobic process because it requires

oxygen.

What are the 3 stages of cellular respiration in order.

Glycolysis, Krebs cycle, Electron transport chain.

What Cellular Respiration Process takes place in the cytoplasm of the cell.

Glycolysis.

In the Prescence of oxygen glycolysis is followed by what

The Krebs Cycle.

One cause of muscle soreness and fatigue is

lactic acid fermentation

What Process is essential in the production of yogurt.

Lactic Acid Fermentation.

T or F Most energy in food comes from sunlight

True

T or F ceelular respiration uses carbon dioxide to convert the chemical energy in organic molecules into ATP

F, oxygen.

T or F The reactants of photosynthesis are the same as the reactants of cellular respiration

False, Product

T or F The Krebs Cycle releases energy that is used to produce ATP

True

T or F The krebs cycle produces electron carrier molecules that play a role in the Electron Transport Chain

True

Cellular Respiration occurs only in the prescense of

Oxygen

The _______ occurs in a series of electron carriers

ETC

Glycolysis converts glucose into two molecules of

pyruvic acid

The body gets rid of lactic acid in a chemical pathway that requires

oxygen.

a high level of lactic acid in the blood is a sign that _______________________________ has occurred

Lactic Acid Fermentation.

What is the difference between an autotroph and a heterotroph?

An Autotroph makes their own food while heterotrophs must obtain there food by eating other animals.

What is ATP and how is energy released from it

Atp is a Energy storing molecule used by cells. Energy is released as atp is converted to ADP

What happens when a phosphate group is removed from an ATP molecule.

When a phosphate is removed from ATP energy is released and ADP is formed

List the three main stages of cellular respiration in order and where they take place

• Glycolysis-Cytoplasm

• Krebs Cycle-Mitochondrial Matrix,

• Electron Transport Chain-Mitochondrial Inner Membrane.

A granum is a

Stack of thylakoids

Does a Thylakoid contain a granum

no

Give me the flow of electrons during photosynthesis

H2o → NADPH → Calvin Cycle.

Where do the light reactions take place

In the thylakoid membranes.

If carbon dioxide is removed from a plant’s environment, what would you expect to happen to the plant’s production of sugars.

Fewer sugars will be produced.

Which region of the visible spectrum is not absorbed well by chlorphyll

green light.

plants take in energy by absorbing

sunlight

which step is the beginning of photosynthesis

pigments in the first photosystem absorb light

what is inside the thylakoid membrane

electron transport chain, photsystems, and atp synthase.

why does the inside of the thylakoid membrane become positively charged during the light reactions

H+ ions are released as water splits.

where are photosystem found

in the thylakoid membrane

what is a product of the calvin cycle

sugar

T or F a plant whose leaves are naturally yellow probably contains chlorophyll as well as other light absorbing pigments

True

T or F if you grind up the chloroplasts found in spinach leaves into a liquid solution the solution will have a green color

True

T or F ATP synthesis is powered by the flow of H+ ions into the thylakoid

False, out

T or F the Calvin cycle provides cells with sugars that can be stored for more than a few minutes,

True,

T or F The light reactions supply the Calvin cycle with CO2 and ATP

Falsem NADPH

thylakoids are arranged in stacks known as

grana

Thylakoids are a _____ color because they contain chlorophyll

green

if you separate the pigments found in a typical plant cell’s chloroplasts you will find ___ orange and red pigments

green

The excited electrons that chlorophyll transfers to the electron transport chain are replenished by electrons from ______ molecules

water

A membrane protein called _________ allows H+ ions to pass through the thylakoid membrane

ATP synthase

The First and second photosystems are both located in the thylakoid membrane what advantage does their closeness to one another provide.

Electrons and energy can easily move through the photosystems, thereby powering each successive step of the light reaction.

What is the role of hydrogen ions in the conversion of adp to atp?

As hydrogen ions pass through atp synthase, ADP becomes ATP

Why are six carbon dioxide molecules rquired to make one glucose molecule.

Each co2 molecule contains one carbon atom. And a glucose molecule contains six carbon atoms.
