Biology Midterm Review

Front

What are the monomers (building blocks) of CARBOHYDRATES?

Back

Monosaccharides/Glucose (simple sugars)

Front

What is the second stage of cellular respiration?

Back

The Krebs cycle

Front

What step does every scientific experiment begin with?

Back

Question/problem

Front

What are the three stages of cellular respiration?

Back

1- Glycolysis, 2- Krebs cycle, 3- Electron transport chain

Front

During glycolysis, glucose breaks into how many pyruvates?

Back

2 pyruvates

Front

What is glycolysis?

Back

The first stage of cellular respiration where glucose is broken down into pyruvate.

Front

What is the role of the Krebs cycle?

Back

To produce energy carriers (NADH and FADH2) and ATP through the oxidation of acetyl-CoA.

Front

What are the products of the Krebs cycle?

Back

NADH, FADH2, ATP, and carbon dioxide.

Front

What is the electron transport chain?

Back

A series of protein complexes that transfer electrons and pump protons to create a proton gradient for ATP synthesis.

Front

What is fermentation?

Back

An anaerobic process that allows for the regeneration of NAD+ from NADH, producing either lactic acid or ethanol.
