How does ATP Synthase work?

The ATP Synthate regulates the ADP and ATP that enters and exits.

What is the purpose of photosynthesis?

The purpose of photosynthesis is to convert water and carbon dioxide to glucose.

What is the purpose of cellular respiration?

The purpose of cellular respiration is to convert the energy stored in glucose to ATP.

Where is energy stored in a molecule?

Glucose.

What is the final electron acceptor in the ETC?

Oxygen.

What is the goal of glycolysis?

The goal of glycolysis is to split up glucose and take its electrons to use later.

What is produced in glycolysis?

2 Pyruvate, 4ATP, and 2 NADH.

What is ATP?

Adenonsine Triphosphate.

What carries electrons from glycolysis and the Kreb's cycle and drops them off at ETC?

ATP.

What is the ultimate source of energy on Earth?

Sunlight.

Where in the cell does photosynthesis occur?

Chloroplasts.

Explain why photosynthesis and cellular respiration are considered complimentary processes.

The products in once process become the reactants in the other and that's why photosynthesis and cellular respiration are complimentary.

What is the chemical equation for photosynthesis?

6C02 + 6H20 --> C6H12O6 + 6O2

What is the total number of ATP produced in cellular respiration?

38 ATP.

Which stage produces the most ATP?

ETC produces 34 of the 38 ATP.

How is the H+ gradient established in the ETC?

The H+ gradient is created when electrons are transported down a chain.

What is the goal of the Kreb's cycle?

The goal of the Kreb's cycle is for more electrons to be gathered for later.

What is produced in the Kreb's cycle?

4CO2, 2 ATP, 6 NADH and 2 FADH2.

What organisms use cellular respiration?

Animals use cellular respiration as well as plants.

What organisms use photosynthesis?

Only plants use photosynthesis.

What is the goal of ETC?

The goal of ETC is to transport electrons down a chain to create a H+ gradient and use H+ to make ATP.

What is produced in the ETC?

34 ATP and water.

What is an autotroph?

An autotroph or produced is an organism that can makes its own food.

What is a heterotroph?

A heterotroph or consumer cannot make its own food.

Three steps of cellular respiration.

Glycolysis (cytoplasm), Kreb's Cycle (Mitochondria Matrix), ETC (Mitochondria Membrane)

What is the chemical equation for cellular respiration?

C6H1206 + 6O2 --> 6C02 + 6H20 + 38 ATP

What is the First Law of Thermodynamics?

Energy cannot be created out of nothing.

What are the two main types of energy?

Potential and Kinetic.
