Glycolysis is a universal metabolic pathway that splits glucose into three-carbon pyruvate molecules, and all glycolytic reactions occurs in cell’s cytosol. After glycolysis, pyruvate enters into the mitochondrial matrix, where a preliminary transition step oxidizes each pyruvate molecule, producing acetyl CoA which then combines with four-carbon molecule in a process called Krebs cycle. This cycle generates CO 2 , NADH, FADH 2 , and ATP which enters into the electron transport chain in the inner mitochondrial membrane.

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

Biology Question

✓ Details Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.
