Thanks!

Thanks so much ellieeet! I'll see if they're right shortly

100% ty

Ellieet was 100% correct. Thank you very much!

1. C) ATP. It's the Energizer Bunny of molecules, providing the necessary kick-start to get glycolysis going.

2. B) Krebs Cycle. It's like the carbon dioxide disco, where molecules break it down and release it with some groovy moves.

3. D) Oxygen. It's the VIP guest at the cellular respiration party, reacting with glucose and setting off a wild energy release.

4. C) 6. Just like a speed dating event, two glucose molecules need six O2 molecules for a successful cellular respiration connection.

5. D) Ectotherms can insulate their bodies and control their body temperature by choice. They're like the cool cats who can play it hot or cold.

6. C) Shivering. It's like a dance party inside your body, fueled by ATP and cranking up the heat like a wild DJ.

1. The molecule that provides the activation energy that starts glycolysis is C) ATP. To get this answer, you should know that glycolysis is the first step in cellular respiration, and it requires energy to get started. ATP is a high-energy molecule that can provide the necessary activation energy for this process.

2. Carbon dioxide is released during B) Krebs Cycle. To determine this, you should be familiar with the different phases of cellular respiration. The Krebs Cycle is also known as the citric acid cycle and occurs in the mitochondria, where CO2 is produced as a byproduct.

3. The compound that is a reactant in cellular respiration is D) Oxygen. This answer can be obtained by understanding that cellular respiration is the process of breaking down glucose molecules to produce energy (ATP), and oxygen is required as a reactant in the final step called the Electron Transport Chain.

4. To determine the number of O2 molecules required for two glucose molecules to undergo cellular respiration, you need to understand the stoichiometry of the reaction. Since each glucose molecule requires 6 O2 molecules for complete respiration, we can multiply this by the number of glucose molecules, resulting in A) 18.

5. The statement that is true is D) Ectotherms can insulate (stop heat loss from) their bodies and can control their body temperature by choice. This answer requires knowledge of the differences between endotherms and ectotherms. Ectotherms are cold-blooded animals that rely on external sources for body heat, but they can still control their body temperature by seeking out warmer or cooler environments.

6. The activity that uses ATP to raise body temperature is C) Shivering. Shivering is a physiological response to cold temperatures, and it requires energy in the form of ATP to stimulate muscle contractions and generate heat to raise body temperature. Panting, hibernating, and storing fats do not directly use ATP to raise body temperature.
