What is lactic acid, and why does it form in our muscles?

An acid that's produced through fermentation when your cells lack oxygen.

State the law of conservation of mass

Mass is neither created nor destroyed in a chemical reaction. The mass of the reactants must equal the mass of the products.

What does the mitochondria do?

The Mitochondria produce ATP energy for the cell. This is where cell respiration takes place.

What does mitochondria require to produce energy?

Glucose and oxygen (Reactants).

What is mitochondria?

An organelle found in large numbers in eukaryotic cells, which is responsible for energy production.

Is cellular respiration and breathing the same thing?

No. Cellular respiration is the reaction that produces ATP energy for cells. Breathing gets oxygen into the organism (inhale) and removes carbon dioxide (exhale).

What does your body do when there is not enough oxygen to support your exercise? (Example: When a runner is sprinting)

It switches to anaerobic respiration (lactic acid fermentation).

Cellular respiration is best described as a process by which

oxygen and glucose are used to make a form of energy called ATP (the energy currency of the cell).

Which word could be used to describe the glucose and oxygen needed for cellular respiration?

Reactants of cellular respiration.

What is an Autotroph?

An organism that makes its own food.

What is a Heterotroph?

An organism that cannot make its own food and needs to eat other organisms for food.

What is the purpose of mitosis?

Growth and repair. Also used to replace dead cells and some organisms use it in order to reproduce.

Longest phase of the cell cycle in which cells grow, maintain normal activities, replicate DNA, and get ready for division.

What is a Chromosome?

Rod shaped structure made of DNA and proteins.

What is the Cell cycle?

An ordered sequence of events in the life of a cell which includes cell division.

Major Stage of The Cell Cycle where the cell divides (4 parts).

What are Daughter cells?

Two are formed as a result of mitosis. They are identical to the parent cell.

What happens in Prophase?

Chromosomes become visible, nuclear envelope dissolves, spindle forms.

What happens in Metaphase?

Chromosomes line up in the middle of the cell.

What happens in Anaphase?

Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell.

What happens in Telophase?

Nuclear envelope reforms around each set of chromosomes. Cytokinesis begins during this phase.

The division of the cytoplasm and the cell membrane. The cell membrane pinches together, and the two daughter cells are complete.
