ADVANCED BIOLOGY 4A

Cells need ____ to perform all their cellular functions and maintain homeostasis

Energy

____ that make their own food

Autotrophs

Autotrophs capture light energy by the process called ____

Photosynthesis

Examples of autotrophs are... (2)

Plants and algae

____ are organisms that depend on other organisms for their energy

Heterotrophs

Examples of heterotrophs are... (4)

Humans, animals, fungi, and most bacteria

____ is the process all organisms (including autotrophs) use to release stored energy

Cellular Respiration

The energy from starch and lipid molecules is too much energy to be used by a cell, all at once, thus these molecules must be converted into smaller, usable units called ____

Adenosine Triphosphate (ATP)

One Adenosine molecule has a combination of... (3)

Ribose - 5-carbon sugar
Adenine - one of the bases found in DNA
Three phosphate groups - (bonded by unstable high energy covalent bonds, bonds break creating a exothermic reaction)

What 4 processes do ATP molecules supply the energy for?

Active transport
Biosynthesis
Cellular movement
Locomotion

With the proper enzymes and an adequate supply of energy, ADP and a phosphate group can recombine to form____

ATP

In ATP, is energy being stored or released?

Stored

If you see ADP, is energy being stored or released?

Released

____ is the process by which certain organisms (autotrophs) can take absorbed light energy and convert it into stored chemical energy

Photosynthesis

Photosynthesis also produces the gas ____

Oxygen

____ , a green pigment, is the primary catalyst of photosynthesis

Chlorophyll

____ reflects the colors ____ ____ and is the most abundant chlorophyll in green plants and serves as the primary catalyst for photosynthesis

1. Chlorophyll
2. Blue-green

____ reflects the colors ____ ____ and is found in seed plants

1. Chlorophyll b
2. Yellow Green

Chlorophyll is found where in the chloroplast?

Grana (pancakes)

Photosynthesis takes place in the ____ of the ____ of the ____

1. Thylakoids (pancake)
2. Grans (pancakes)
3. Chloroplast

The light dependent phase requires light energy to be absorbed to energize ____ in a chlorophyll a molecule

Electrons

Water is split by the process called ____

Photolysis

A series of protein molecules is

Electron transport chain

Which process do the H+ ions concentration within the thylakoid causes active transport of the H+ ions to be pumped through a protein (enzyme) in the thylakoid membrane

Chemosmosis

The protein in the thylakoid membrane is called what?

ATP synthase

When chemosis is finished, what is formed?

ATP
