Answer 1

Answer [Q-37]: a. True

Explanation: Glycolysis is a process of conversion of glucose into pyruvate in order to generate energy. During the energy generation phase of glycolysis, ATP is synthesized. During this synthesis 1- phosphate group is transferred from an acid anhydride from the molecules involved in the process. This attaches with ADP (Adenosine DiPhosphate) to form ATP (Adenosine TriPhosphate).

Following is the process:

ADP + Pi ----> ATP

Answer [Q-38]: a. Carrier

Explanation: There are two types or transporter proteins. Channels proteins and Carrier proteins. Carrier proteins are the ones which carry selective molecules like sugars and amino acids across the membrane.

Incorrect answers:

b.) Channel: Protein 1 is the channel protein. They are open on both sides inside and outside, allowing the the particular molecules or ion to pass easily.
c.) Cell identity: Carbohydrates attached to the proteins help in Cell identity. So more than one protein in the diagram can help to identify the cell type.
d.) Receptor: They are the proteins that help to transfer signals and information. These proteins have receptors that bind with the chemical carriers such a hormone.
