What is Homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions. It involves balancing various physiological processes.

Front

What type of cell is most likely prokaryotic?

Back

Prokaryotic cells are simple, single-celled organisms without a nucleus. An example is Cell B.

Front

What is an example of homeostasis in the human body?

Back

The regulation of blood sugar levels, where insulin is secreted after meals to lower blood sugar and glucagon is released between meals to raise it.

Front

What is NOT a function of Proteins?

Back

Short term energy. Proteins primarily serve as enzymes, structural components, and play roles in immune response and cell signaling.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to drive the synthesis of glucose during photosynthesis.

Front

Define Prokaryotic Cell.

Back

A prokaryotic cell is a type of cell that lacks a membrane-bound nucleus and organelles, typically found in bacteria.

Front

What is the function of enzymes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

Front

What is the significance of glucose in cellular respiration?

Back

Glucose is a primary energy source for cells, and it is broken down during cellular respiration to produce ATP.

Front

What is the difference between positive and negative feedback?

Back

Positive feedback amplifies a response or process, while negative feedback reduces or dampens it to maintain homeostasis.

Front

What is the role of insulin in the body?

Back

Insulin is a hormone that helps lower blood sugar levels by facilitating the uptake of glucose into cells.
