Keystone Biology Module 1 part 2

Front

What is the role of the Golgi apparatus in protein transport?

Back

The Golgi apparatus processes and packages proteins that have been synthesized in the endoplasmic reticulum (ER) before they are sent to their final destinations.

Front

What is the main difference between active transport and passive transport?

Back

Active transport requires energy (ATP) to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

How does photosynthesis relate to cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are essential for cellular respiration, while cellular respiration uses glucose and oxygen to produce energy (ATP), carbon dioxide, and water.

Front

What are the key molecules involved in protein synthesis?

Back

The key molecules involved in protein synthesis are mRNA (messenger RNA), tRNA (transfer RNA), amino acids, and ATP (adenosine triphosphate).

Front

What is the function of ATP in cellular processes?

Back

ATP provides the necessary energy for various cellular processes, including protein synthesis, muscle contraction, and active transport.

Front

What is the significance of oxygen in cellular respiration?

Back

Oxygen is essential for cellular respiration as it acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is the difference between photosynthesis and cellular respiration in terms of gas exchange?

Back

Photosynthesis produces oxygen as a byproduct, while cellular respiration consumes oxygen and produces carbon dioxide.

Front

What is the primary function of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating mRNA into amino acid sequences.

Front

Define active transport in biological systems.

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy input.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in plants that absorbs light energy, primarily from the sun, which is used to convert carbon dioxide and water into glucose during photosynthesis.
