Cell Energy Study Guide

Autotrophs get energy from
the sun

Heterotrophs get energy from
eating food

What does ATP do for the cell
It’s an energy storing molecule

Does ADP have stored chemical energy usable for the cell

What is the difference between ATP and ADP
ATP has usable energy for and ADP doesn’t

What organelle performs photosynthesis

What process converts light energy into chemical energy

What are the 3 stages of Photosynthesis
1. Absorption of light= Primary pigment chlorophyll
2. Conversion of light energy to chemical energy
3. Storage of energy and organic molecules= Calvin Cycle

Which stages would be considered a light reaction
Light reactants

Which stages would be considered a dark reaction
Calvin Cycle

What pigment absorbs light on the thylakoid membrane

What does photosynthesis release into the air

What are the reactants of photosynthesis

What organelle performs cellular respiration

What process releases the chemical energy stored in food
Cellular respiration and photosynthesis

What are the 2 stages of cellular respiration
1. Breakdown of organic molecules= Stage name: Oxygen
2. Production of carbon dioxide= Calvin Cycle

What does cellular respiration release into the air
Carbon Dioxide

What are the reactants of cellular respiration

What are the products of photosynthesis

Is the mitochondria used for aerobic respiration

Is the mitochondria used for anaerobic respiration

How are photosynthesis and Cellular Respiration related
By some molecules at use but they are switched

what organelle is used in cellular respiration if oxygen is present

What is it called when respiration as oxygen

What happens if oxygen is not present

When would a cell produce the most ATP, with or without oxygen
With Oxygen

Why do plants have mitochondria
Because it turns glucose into energy

What is anabolic
one that involves creating large molecules out of smaller molecules

Why are more chloroplast found in leaves of plants
Because the surface area is bigger

Why does change color in the fall
lack or chlorophyll

Which steps in respiration are anaerobic
Glycolysis and Fermentation

Where does oxygen used in respiration end up
ends up in water

Define photosystem and pigment
Main Pigment: Chlorophyll, Pigment: Colored substances that absorbs or reflects light, and Photosystem: Cluster of pigments

What bonds are broken to release energy during photosynthesis

Energy is trapped in the cell in 2 ways

What is the total break down of ATP in each step in respiration
Glycolysis: 2, Krebs Cycle: 2, Electron Transport chain: 32

What is the difference between alcoholic fermentation and Lactic Acid Fermentation
Alcoholic: takes place in yeast and bacteria
Lactic Acid: Builds up in muscles

What is the most important energy storing compound
