Unit 3 Section 1

Front

What is glycolysis?

Back

Glycolysis is the anaerobic process of breaking down glucose into pyruvate, producing a small amount of ATP and NADH.

Front

What are the end products of glycolysis?

Back

The end products of glycolysis are 2 pyruvate molecules, 2 ATP (net gain), and 2 NADH.

Front

What is the role of ATP in cellular respiration?

Back

ATP (adenosine triphosphate) serves as the primary energy currency of the cell, providing energy for various cellular processes.

Front

Define autotrophs.

Back

Autotrophs are organisms that can produce their own food using light or chemical energy, such as plants and some bacteria.

Front

Define heterotrophs.

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy, such as animals and fungi.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the Krebs Cycle?

Back

The Krebs Cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to produce ATP.

Front

What are the inputs of the Krebs Cycle?

Back

The inputs of the Krebs Cycle include acetyl-CoA, NAD+, FAD, and ADP.

Front

What is the main purpose of the Krebs Cycle?

Back

The main purpose of the Krebs Cycle is to produce electron carriers (NADH and FADH2) and ATP for use in the electron transport chain.
