Unit 1 - 4 AP Bio Review

Front

What is the principle of energy input in cellular processes?

Back

Energy input must exceed energy loss to maintain order and power cellular processes.

Front

What is the phenotypic ratio in a dihybrid cross of complete dominance?

Back

The phenotypic ratio is 9:3:3:1.

Front

Why is water considered a polar molecule?

Back

Water is considered polar due to its polar covalent bonds.

Front

What are lysosomes?

Back

Lysosomes are membrane-enclosed sacs that contain hydrolytic enzymes.

Front

What is the difference between active and passive transport?

Back

Active transport uses ATP (energy) while passive transport does not need energy.

Front

Define active transport.

Back

Active transport is the movement of molecules across a membrane using energy (ATP).

Front

Define passive transport.

Back

Passive transport is the movement of molecules across a membrane without the use of energy.

Front

What is a dihybrid cross?

Back

A dihybrid cross is a genetic cross between individuals that differ in two traits.

Front

What are hydrolytic enzymes?

Back

Hydrolytic enzymes are enzymes that catalyze the breakdown of compounds by adding water.

Front

What is the role of the Golgi complex?

Back

The Golgi complex modifies, sorts, and packages proteins and lipids for secretion.
