which statment is true
is it cellular respiration begins with the krebs cycle in the cytopiasm, cellular respiration begins with glycolysis in the cytoplasm, cellular respiration begins with the krebs cycle in the mitochondria, cellular respiration begins with glycolysis in the mitochondria
The true statement is:
Cellular respiration begins with glycolysis in the cytoplasm.
which term describes a product of photosynthesis
is it carbon dioxide, glucose, energy, water
The correct answer is glucose. Glucose is one of the primary products of photosynthesis.
if producers generated 100% of the energy what percentage of that energy is left by the time it reaches teritary consumers
Typically, only about 10% of the energy from one trophic level is transferred to the next trophic level. Therefore, if producers generated 100% of the energy, by the time it reaches tertiary consumers, only 10% of that energy would be left.
The statement that is true is "cellular respiration begins with glycolysis in the cytoplasm."
To determine which statement is true regarding the beginning of cellular respiration, we need to understand the steps involved in this process. Cellular respiration is the metabolic pathway that converts glucose molecules into adenosine triphosphate (ATP), which is the main source of energy for cells. It consists of three main stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation.
Now, let's evaluate each statement individually:
1. "Cellular respiration begins with the Krebs cycle in the cytoplasm." - This statement is incorrect. The Krebs cycle, being the second stage of cellular respiration, does not occur in the cytoplasm, but rather in the mitochondria.
2. "Cellular respiration begins with glycolysis in the cytoplasm." - This statement is true. Glycolysis is the first step of cellular respiration and takes place in the cytoplasm of the cell, not in the mitochondria. During glycolysis, glucose molecules are broken down into two molecules of pyruvate, producing a small amount of ATP.
3. "Cellular respiration begins with the Krebs cycle in the mitochondria." - This statement is incorrect. As mentioned earlier, the Krebs cycle occurs within the mitochondria, but it is not the initial step of cellular respiration.
4. "Cellular respiration begins with glycolysis in the mitochondria." - This statement is incorrect. Glycolysis, the first stage of cellular respiration, occurs in the cytoplasm, not in the mitochondria.
In conclusion, the correct statement is: "Cellular respiration begins with glycolysis in the cytoplasm."
